Obsidian Piledriver
The obsidian piledriver is like a pizza being thrown into the air and then slammed back down. Your partner is the pizza, and you are the person throwing it.
My boyfriend did the obsidian piledriver and I got a headache from laughing too hard.
My dad tried the obsidian piledriver and got a sore back.
My friend did it in the park and everyone watched.
