Toboggan Donkeypunch 

Same definition as Donkeypunch with the exception that it is performed at the top of a staircase, and when you deliver the punch, the giver pulls the receivers arms back and rides them down the staircase-like a toboggan.

"Your mom was giving me some attitude during anal, so I gave her a toboggan donkeypunch."
"I swear to god the next time someone tips 10% on a $500 tab, I'm going to toboggan donkeypunch their whole family."
