Can we please just define some semiobscure little hand signal that means "yes, I want to sleep with you, OVER" . . . how often do you think it happens where two people pass each other in the street/morgue/bottom-of-the-nile and they both totally want it, but society requiring the existence of a bar in any room where such proposals are made causes them to stay stone-faced until out of sight?  Very frustrating, if only because my no-game ass would get a kick out of watching the frat guys looking like third base coaches.  ONLY UNLIKE THE COACH THEY'D BE QUITE FAR FROM THIRD BASE YESSSSSSSSSSS THAT'S THE WINNER BYE
