(B)ag (S)hag (A)nd (R)elease

(pronounced like "bizarre")

Shorthand for a one night stand.

Often used after a hook-up goes horribly wrong.
Guy #1: How was your night?

Guy #2: BSAR man...I hooked up with that one chick with the split tongue we met at the hookah bar.

Guy #1: Oh, how was it?

Guy #2: I got out there as soon as she brought out the chains, whips, and electrodes.
