When a man is doing a woman from behind, the woman sneakily puts on a strap on (preferably made of a tough plastic complete with coloring). As the man is about to thrust inward, the woman shifts her balance so the man falls to the bed/tabletop/elevator floor/wherever the mating is occuring, and then the woman jumps on his back as he is still utterly confused and begins to bang him relentlessly in the asshole.
One time in Las Vegas I was screwing this prostitute doggy dog style when she unexpectedly turned on me and pulled the bait n strap on me and then hit me with a role of salami.
Bar game for when a guy has successfully hooked up with the fattest girl in the club . Once a hook-up has been assured(girl agrees to leave for sexual reasons), the suitor will gesture to his buddies that he is wrapping an invisible
belt around his waist like a WWE wrestler. The victor drinks for free the following weekend.
After the behemoth at the bar broke her third barstool, Ted helped her up and they immediateley headed for the door. Ted flashed the strap on the belt sign on his way out, a clear winner of Saturday's main event.
