Reference to one of the best songs ever by Eminem called "Stan" about an Obsessed fan who ends up killing himself and his wife over Eminem not writing him back.
Basically it describes someone who is all up on their favorite artist's schlong, and can't take criticism or the slightest negative about said artist. But instead of "fans", they're called "Stans", get it?
Me: Man I just got rid of all the Jay-Z shit on my Computer
Homie: For Real?
Me: Yeah, Jay-Z Stans can go eat a dick
