Boss Hog

The act of pinching your foreskin just prior to ejaculation so as to create a seal, preventing the semen from exiting. Results in the foreskin bloating like a water balloon. The foreskin is then let go, releasing the semen, usually onto another person. Can also be performed with urine. Is considered by many to be highly arousing, sometimes performed as an alternative to traditional coital acts.

Tim: "Hey did you see Henry on Cath lastnight?"

Peter: "Yeah, looked like he was boss hogging her!"

Tim: "Oath, his foreskin looked like a basketball!"
