Obsidian Piledriver
The obsidian piledriver is when someone takes their partner’s junk and uses it like a trampoline. They bounce them up and down like a madman with a boner.
At the party, John did the obsidian piledriver to Sarah and the whole room laughed.
My mom tried the obsidian piledriver and broke her neighbor’s nose.
My brother does it every time he sees a hot girl.
