Upper Michigan Dump Truck 

You're fucking a girl from behind. She has her head down UNTIL you stick your thumb in her ass (thumb warmer). The surprise of a thumb going in her ass makes her raise her head (presumably with her mouth open) at which point your buddy takes a shit in her mouth.

Me and my buddy gave Tom's mom an Upper Michigan Dump Truck

Upper Dorker Door Dumper 

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!
