Gay luigi originates from the philips CD-i videogame, "Hotel mario". When mario and luigi are entering the mushroom kingdom after being invited by the princess to a picnic, mario tells luigi, "Nice of the princess to invite us over for a picnic, eh luigi?". Many people mistook, "Eh luigi?", for, "gay luigi?".

v. A verb inspired by both a Youtube Poop and Dave Chapelle's definition of a "stranger"; when performing a Gay Luigi, one constantly eggs on someone until they say "Fuck you!", and then you yourself reply, "No, YOU, (person's name)". You then proceed to anally rape the person.
Know what I like to do when I get a massive hard-on? I like to make fun of people until they say to me, 'fuck you!'. I then say, 'no, you', and then I rape them. I call it, a Gay Luigi. Have you ever felt a Gay Luigi?
