look up any word, like bangarang:
1: The most underrated Nintendo character, and also my favorite. He wears a green shirt with blue overalls, and a green cap with the letter 'L' on it (Although back in SMB1, he wore white with green overalls), and was underrated and overlooked until he got his own game.
2: The best character in Super Smash Bros. Melee, no doubt. Much better, in fact TIMES better than Mario in all aspects of combat, with useful smash moves and devastating aerial attacks.
It's no wonder you have to unlock Luigi, he's so damn good. Fuck Mario, let's give Luigi props for a change.

1. A slang term meaning simply moustache. Named after the character from Super Mario Bros (Mario doesn't have the same ring to it).

2. "Growing a Luigi". A term for the stubble found on adoloscent boys when they attempt to grow a moustache after entering puberty.
1. Andrew: Nice Luigi you have there, Matt.

2. John: Tim, you growing a Luigi? At least you're trying.
