The title has "fuck" in it, but the show is not based on sex (although a few episodes portray it); instead, the "fuck" part is more like "screwing over", which is what Fudêncio does to Conrado.
In "Corrida Mambembe", Popoto keeps pressing his cart's horn, but since the horn can't be seen on-screen, it looks like he's masturbating.
Adaptation Displacement: The cartoon character Fudêncio is nowadays much more well-known than the real-life doll that inspired him. Nowadays, Fudêncio e Seus Amigos is the most remembered Brazilian MTV cartoon, and is still fairly obscure due to not airing on TV since 2013.
Alternate Character Interpretation: Is Conrado a nice guy who was corrupted by the world he lives in, or just a prick who thinks he's above others and has an ego too high for all the bad luck he has?
During "Corrida Mambembe", there are some scenes of the episode that show Funérea watching TV, and later, she appears in the program herself. These scenes have no relation with the main race plot. They were most likely added so viewers wouldn't be wondering why Funérea isn't in the race.
Near the end of "Instituto Médico Legal", there's a random Cutaway Gag where Teacher Cudi and her boyfriend (who has a live-action head) watch TV in a bed, with the woman in the program saying a line heard in a soap opera seen in an earlier episode but in Spanish. After that, the episode concludes normally. This gag comes out of nowhere and adds nothing to the plot.
Creator's Pet: Peruíbe in the later seasons. He always shows up and has large roles, while even the main trio doesn't get as much focus as him (although Funérea gets a bit more due to being both the Creator's Favorite and the fans').
Ensemble Dark Horse: "Homem do Saco" (Sack Man) from "Quiprocó na Lama". He is a play on the myth of the "sack man", who kidnaps bad kids and puts them on his cloth sack... Except the sack man from this series is naked and has a giant ballsack. Even people who don't like the show liked this gag; in online forums, some people who watched the three-episode premiere on the night of August 23, 2005 state that he was the only thing they found funny about the show.
Fandom Rivalry: With Jorel's Brother. Fans of this show usually hate it for being new and not having the same humor as Fudêncio, while fans of that show hate this one for being too heavy and inappropriate.
The very first episode, "Quiprocó na Lama", has the kids going on a trip to the brazilian state of Minas Gerais to ski in mountains of mud. Ten years later, in 2015, a mud barrage in Minas Gerais broke, flooding a city and killing many people; something that happened again, in another city of the same state, in 2018.
A Couch Gag during the title narration was the narrator saying "Distribution:", followed by a random word or phrase as if it was the name of the episode's distributor. Nowadays, the show is not distributed at all, so that feels a bit sadder.
In the third-to-last episode of season six, Fudêncio destroy tapes of all episodes of the show at MTV. Two years later, the original MTV Brazil ended, and several episodes of the series became Missing Episodes.
The episode "Bola Gato" as well, where all of a porn studio's scripts are permanently lost. Turns out this show has had some scripts lost too, though probably not permanently, as the lost episodes' tapes are currently waiting to be digitalized along with every other tape belonging to MTV Brasil.
In the 2010s, a while after this show ended, "mimimi" (Fudêncio's trademark One-Word Vocabulary) became an expression used to mock people complaining, especially if it's for a stupid reason. Since Fudêncio is such a politically incorrect show, it ends up being very likely to make people "mimimi", just like Fudêncio!
Caused Creator Backlash after the show creators noticed people were using the expression even to mock people who make good points and didn't say anything wrong.
In the show, Fudêncio is treated well and praised for his actions even though he always does bad stuff. Among the fans, Funérea is treated the exact same way.
In the Season 2 episode "Teste de DJ", Conrado applies for a test to be a MTV VJ. In Season 4, he gets a new voice actor who was a MTV VJ during the time the show was airing.
In "Ponte de Safeno", a season 1 episode, Safeno becomes healthy after Conrado's body organs are transplanted to him (without permission). In Season 5, Safeno's voice actor also becomes Conrado's new voice actor.
Many people only watched the show because of Funérea, and her acid personality, with both Fudêncio and Conrado having some negative reputation among fans.
Some other people only watched it because a NSFW program was shown immediately after.
Conrado was the favorite character of some fans, who watched it because they relate to him always "getting fucked in this shit".
After the then-MTV VJ Felipe Solari began voicing Conrado, his fans started watching the show because of his participation.
Fudêncio was originally a plastic doll shown in a real life program in 1997.
The term "mimimi", while popularized by this show, was already used before; either as an onomatopoeia for cats or to mock someone like "blah blah" (which is closer than the current meaning). Some more ignorant people also attribute it as being the trademark cry of the titular character of El Chavo del ocho, even though this one was actually pipipi.
Periphery Demographic: Despite being 14+, several younger kids watched it anyways; the creators have talked about cases where some parents would watch it along with their children.
Memetic Bystander: Homem do Saco, especially because he also makes cameos in other episodes.
Memetic Mutation: Each of the main trio has had a catchphrase of theirs become a meme; Funérea's "what a misfortune", Conrado's "I only get fucked in this shit" and Fudêncio's One-Word Vocabulary "mimimi" (which, for the reasons mentioned in Hilarious in Hindsight, is used even by people who don't know or watch the show).
Replacement Scrappy: Several Season 5 and 6 episodes had another character teaching the kids instead of Mrs. Cudi, but she was much missed in these.
Seasonal Rot: Seasons 1 to 3 are widely considered the best, as each posterior season has changed more to worse:
Season 4 changed Conrado's voice actor and replaced the old paper title cards with chalkboards, which often didn't have drawings of Fudêncio and Conrado like the paper ones. Plus, while the title narrator hadn't changed yet, he wasn't as much of a Large Ham as before.
Season 5 had less episodes focused on Fudêncio and Conrado, the two main characters, and sometimes, they wouldn't even appear at all.
Season 6 had the same problem as Season 5, having a sub-plot involving Teacher Cudi's love life. It also replaced the Large Ham title narrator with either a regular narrator or a crazy, but more calm, voice (even though the previous narration was done by the creator of the show and he was still there), lacked the nasal-voiced narrator after the first episode, suddenly turned Kevin Costa into a pig, and changed Conrado's voice actor again, along with Zé Maria, Delcídio and Safeno.
In "Folclore do Caqui dos Outros é Refresco", an animation of Conrado walking holding a laptop is reused from the previous episode "O Que Está Acontecendo, Conrado?". The problem is that, in the original episode, Conrado had pimples all over his face, which were kept in the reutilization despite Conrado not having any pimples before or after that scene.
Similarly, in "Os Segredos da Peida", there's a brief scene where Peruíbe lifts his shirt, exposing his belly and a big scar on it. The original animation was made in "Prenda Prendida Prendada", where Conrado showed a scar he got from being punched; in Peruíbe's case, not only was the scene completely unnecessary, they didn't even remove the scar so it appears for no reason (they did just recolor the skin).
In a scene in "Futibas Church", Peruíbe is talking in front of the class, but when the camera switches to the group shot of all the students, Peruíbe appears there as well. The same error occurs with Neguinho in "Rei do Pop".
Take That, Scrappy!: Fudêncio getting punched by Funérea in "Chavonildo", especially since they're the most hated and loved characters of the show respectively. The Laugh Track that plays in that scene is even accompanied by cheers and claps.
Tear Jerker: Conrado's unlucky life, while Played for Laughs, can often be very saddening. He's the Only Sane Man in this world and not only has to endure being ridiculed by his classmates (especially Fudêncio), he often gets severely punished for things he never even did or misunderstandings. Plus, he comes from a very poor family, with an unemployed (and abusive) father and addict mother.
They Changed It, Now It Sucks!: When Conrado's voice actor was replaced in Season 4 by Felipe Solari, most of the fans hated the character's new voice. He sounded nothing like the old one and even spoke differently; the people who did like the new voice were mostly fans of Felipe Solari. Then his voice changed again in Season 5 and both fans of the first and second voice hated him.
Unintentionally Sympathetic: Funérea is rude and mean to the other characters for no reason, disrespects everyone including the elders, and does not care about other people's problems. She is still the fans' favorite character, being loved by almost all of them and even praised for her acts. It probably helps that she's not outright evil like Fudêncio.
Unintentionally Unsympathetic: Conrado is portrayed as a nice and smart guy who always does the right things, and gets punished unfairly. Some fans, instead of feeling sorry for him, hate him because of how boring and annoying he can be, and at least one of his voices. That said, these fans still hate Fudêncio because of what he does to Conrado.
In the episode "Astronauta de Árvore", made in 2005, Fudêncio and Conrado "discover" a new planet called Acre (which in reality, is just a Brazilian state). After this, a news report is shown saying Acre is the tenth planet of the Solar System. If the episode were even one year older, it would say "ninth planet" instead, as Pluto was declasified as a planet in 2006.
"Emorruídos", which premiered in late 2007, is about an emo band performing at the school. All the students become emos as well.
In "Menino Diabo", the ad for the website "galerinha.com" has a very 2000's aesthetic, with vintage filters and flashing words. In the same episode, the social media Orkut is seen.
The social media Orkut is mentioned in "Loira à Rodo". It was very popular in 2010, when the episode aired, but lost popularity a few years later and was discontinued in 2014. Now, it's just a nostalgic memory.
Viewer Gender Confusion: Zé Maria's gender left (and still leaves) many viewers confused on whether she's a trans girl, a boy dressed as a girl, or a cis girl with a deep voice.
What Do You Mean, It's Not for Kids?: The child characters' cute designs seem like they are from a children's cartoon, but they're definitely not. YouTube's infamously broken COPPA system seems to disagree with certain uploads of certain episodes, though. Particularly, uploads from the episodes "Cotas de Cocotas", "Gemiocídio", "Foi-se o Martelo" and "Mundial Surreal" get hit by this the most frequently.
The Woobie: Conrado, so much that he complains about always getting fucked almost Once an Episode. He is always getting hurt, receiving negative points from his teacher, getting arrested, and almost always because of Fudêncio, who never gets any comeoccupance.
