A phrase pertaining to quick masturbation. Typically used when someone is in the bathroom for longer than required for a standard "Number 1", though a bit too short to assume it was "Number 2". One could infer that he / she was "peeing with a kick". This time frame is usually between 2 and 3 minutes.
Josh: "That was either a really quick dump, or a massive piss."

Michael: "I bet he was just peeing with a kick."
