The act of receiving/giving an outside/inside of the pants hand job whist mid-dance. Usually preformed in the later hours of a long night of clubbing. The act is most often unsolicited and spontaneous.
Friend: What the hell was that girl in the hookers uniform doing to you with her hands?
Receiver: Dude, I gotta go clean up my pants, she just gave me a dance job and I splooged in my undies.
