When a skinny white boy gives his girl anal and her poop gets on his dick. The slang name comes from when you get a vanilla cone from Dairy Queen and get it dipped in chocolate. It is customary for the girl to lick the guys dick clean following their anal session
Jordan: Yo I just had a vanilla cone dipped in chocolate last night with my fiancé

Jesse: you mean where you did her up the booty?
Jordan: yes it was awesome
Jeff: did she do the customary licking your dick clean afterwards?
