Two common uses;
1. A sincere expression of the worth of a womyn. If you're a feminist, used when one comes across a soul-partner which one is willing to co-habit with in an egalitarian, non-gender-traditional way. If you're not, used when one comes across a chick with junk in da trunk.
2. A complaint to restaurant management in New York City used by Rob Reiner and other bleeding-heart liberals with nothing else to do with their time.
2. Excuse me, sir. Despite the recent blanket ban on doing so within a restaurant, that bitch is smoking. If you do not eject her from the eating area without delay, I will be forced to sue.
