shoving your index finger into an unsuspecting open mouth
some dumptruck at a bar won't quit yapping her hussy face off; rather than insulting her and her friends or trying to continue to just get laid, wait for an obnoxious laugh and pop your entire finger into her mouth while saying "[dick in your mouth! DIYM". conversation satisfyingly over, and at least you get a good laugh out of it.
