When a guy is doing a woman from behind and is taking too long to finish (whisky dick). After a prolonged period of boredom and frustration the woman eventually becomes enraged (like a mama bear defending her cub). She then reaches between her legs and squeezes his sack as hard as she can until either he finishes or escapes.
Barry had total whisky dick last night and took forever. I finally had to give him the bear claw.
