When you try to fistbump someone who is trying to high five you, and you get into that awkward high five-fistbump tango looking like both of you are grabbing boobs back and forth.
Man I got into a bad boob grab situation with my coworker last night at the afterwork, she was trying to high five me while I was trying to fistbump her.
