slow moshing 

A combination of slow dancing mixed with a mosh pit, all participants are in pairs dancing haphazardly, most likely drunk and/or high, and one couple will bump into another causing a domino or chaos effect that could lead to spinning girls used as projectiles, tango donkey punches, fist fights, or extreme laughter and fun, depending on the crowd.

Adam: "What is wrong with your ankle?"

Gabrielle: "It must have been injured last night while we were slow moshing, I didn't notice how swollen it was until today because I was laughing so hard and having too much fun to notice last night..."
