The Carolina Shim-Sham

A famous dance move, originating in North Carolina. Those who have mastered it are feared by all, namely because of their top-tier dancing skills, and not because the dance involves squatting to the floor and skinning yourself alive.

"Dude, what move was that?"

"The Carolina Shim-Sham."
"Never talk to me again."
"Please take me to a hospital."
