Spontaneous Mustache

THIS is what a REAL mustache looks like!^note "Is he a mermaid?"

"I grew this mustache through sheer force of will, don't tell me I'm not ready."

— Gordito Delgado (age twelve), The Adventures of Dr. McNinja

This trope occurs when someone (often someone who should not be able to grow facial hair at all) grows a beard or mustache just by willing it. Naturally a sign of extreme manliness and a sign of extreme silliness.

Compare Girls with Moustaches, Perma-Stubble, Perma-Shave, and Manly Facial Hair. Not related to Growing the Beard.

Then Dennis rips those fake mustaches off of their faces and then shows them what a real mustache looks like — by opening his mouth covering and then instantly growing a bushy mustache. Patrick wonders if Dennis is a mermaid too.

Live-Action TV

• In one episode of Cheers the guys at the bar have a beard-growing contest with none of them shaving for a month, and whoever has the longest beard at the end of the month wins.

On the last day of the contest Cliff enters the bar with an epic beard, saying it grew in overnight. After he wins the contest, he is on the phone with a superglue company asking what happens when it comes into contact with human skin - he cheated by supergluing the hair to his face and now he needs a doctor.
