a cousin eddie
A cousin eddie is when you're going down on a girl and you pull out and jam it up her ass while yelling ‘Shitter’s full!’ like it’s the last thing you’ll ever say.
He was going down on her and suddenly pulled out and jammed it up her ass. He screamed ‘Shitter’s full!’ and it was so loud I heard it in the next room.
He did a cousin eddie in the hallway and the whole school ran out of the building.
He did a cousin eddie in the middle of a math test. I got a D because I was laughing too much.
