a quick but painful pinch on a man's nipple

The phenomenon of having to come out as bisexual to the same person/people repeatedly because they assumed or hoped that your sexuality was a "phase." Refers less to the holiday and more to the 1993 Bill Murray comedy film in which the main character experiences the same day over and over.

The act of one man quickly striking with his nails or fingers at another mans nipples with precision. The goal is to quickly pinch and or twist another mans nipple until a thick red juicy substance leaks out of there body creating a burning and stinging sensation. Best works on fat people since you will have a better chance at locating nipples.
