1. A social gathering to watch porn.
Background info: Invented by two guys who were really bored one day and their minds went off into random topics. The topic of porn watching came up and thus we wished to find one word to describe this event. We came up with "groker," a fusion of the screennames held by the two gentlemen: "green" and "joker."
Hey let's go to the groker later tonight, all the guys and girls are going to be there and it's going to be a lot of fun.
