This is a combination of the Upper Decker
and the Door Dumper
, with a twist.
You find the dorky friend of your adversary, stuff him in a garbage can, take a shit on him, fill the can with water, lean it against your adversaries’ door, knock and walk away. When he opens the door, he is flooded by the smelly water and his shit-covered friend.
That guy is such an asshole, I’m going to find his dorky friend and give him an Upper Dorker Door Dumper!
