For when a friend goes to bump fists with you and instead you quickly clamp your hand over theirs. It's supposed to feel unpleasant; a mean-spirited fist bump.

Occurs when one circumsized male touches penis's with another male who is uncircumsized so that the foreskin covers the tip of the uncircumsized penis joining them as one or as a trailer hitch. (Although I don't recommend heavy towing wink wink)
