2. Anything to do with drugs in multiples of three. For example, having three bowls being passed in a circle, doing three hits of acid at once or doing three lines of molly at a time.
Dude 2: "Don't a pussy dude, go for the Triple Wide!"
Dude 3: "Yeah dude, here I just poured you two more shots."
Dude 1: "Fuck yeah, I did the Triple Wide, damn, I'm fucked."
