YMMV / RanguGamer

• Aluminum Christmas Trees: During Federico19's first mentions on the channel, he was only meant to be a name for a fake youtuber for Rangu to jokingly insult and to talk about clickbait. However, later on, he discovered that a youtuber called Federico19 did exist, which surprised him a lot.
• Continuity Lockout: As Rangu himself has stated, multiple people that watch his videos have a hard time understanding them because of the gigantic amount of inside jokes and running gags in them. This is a fact that Rangu revels in.
• Fanon Welding: It has become a popular headcanon that Chansilla and Topi from KiaraFey's Pokemon playthrough are somehow related, since the two of them are extremely adorable characters who spam Metronome to catastrophic results (in Chansilla's case, it's catastrophic to her opponents, in Topi's case it's catastrophic to him) and since Kiara is a good friend of Rangu.
• Memetic Badass: Chansilla, a Chansey that became the best fighter in Pokémon Yellow and received a Running Gag about being a tough mofo that annihilated all her enemies. Especially notable because he and Eric never thought that Chansilla would amount to much at first.
• Memetic Mutation: An image of Rangu pointing at the viewer with a gigantic line of "XDDDDDDDDDDDDDDDDDDDDDDDD"s behind him, is commonly used to make fun of something or someone, and it's usually used alongside an audio of Rangu laughing at the top of his lungs.
• Play-Along Meme: It's pretty common for people to joke about DinoPrehis (a joke between Rangu and Eric about an anime about a fake Mon game) being an actual anime and claiming that it influenced series like Digimon, Yugi-Oh and even Pokemon itself. This became Hilarious in Hindsight when someone actually started developing a real DinoPrehis fangame.
