octopus clap
When two women slam their crotches together so fast it makes the whole room feel like it’s getting a wet slap from a very angry duck.
At the mall, my friend and her crush did it and the security guard came running.
They did the octopus clap in the restaurant and the waiter dropped the plates.
At the sleepover, my sister and her friend did it and it was the best part of the night.
