NOTE: For use in humorous settings.
Originating from old internet macro image with title text and a beardy black man with a nasty stare.
Tag appropriate when someone in an image has a psychotic facial or other expression making them look like they'd be about to commit the deed; menacing shadows may also be a qualifier. Target of action need not necessarily be present in said image. It does NOT mean someone is vulnerable, quite the opposite.
For pictures where the subject is literally gonna get raped (in a not particularly humorous fashion), consider using the tag imminent_rape instead.
Nobody here but us chickens!
