when you see someone you know and they offer you there hand for a greeting shake as one would at a business interview. However at the last second they try and do some fancy bro shake with you ending in epic fail on all accounts. This usually leaves the unsuspecting recipient feeling ashamed and less then a man.
(Situation: At the club in front of some girls and you get shake raped by a bro)
girls: hahahaha you totally fucked that up you must have a small penis
you: fuck that!, I just got shake raped.
