When you hold up four fingers in the vulcan salute then uppercut a womans vagina, making sure both sets of fingers penetrate a hole. Must also be accompanied by yelling "vulcan punch!" or rape charges may be a consequence.

A particularly violent cross between doing it bareback and a donkey punch. For the uninitiated, this means the act of having sex doggy style and then punching the girl in the back of the head.
Things got a little boring between me and Melissa so I Bareback Vulcan Punched her. I haven't talked to her since.
