A fuapa is the sad-looking thin mustache originally worn by Mexicans. But they are now sported by pathetic teenagers who can't grow manly 'staches. A fuapa is usually only on the sides of the upper lip and they should just shave that shit.
Stevie couldn't produce enough testosterone for a real mustache therefore he was stuck with a fuapa.
