A German Slotter Punch is when a guy is doing a girl missionary style, he puts his hard penis between her vaginal lips and then punches them both in the joined area. Can also be used on the anus as well. Is suppose to be very enjoyable for both parties but, if it just causes pain you are punching too hard.
Guy: Hey dude did you try that new move with your girl I told you about? The German Slotter Punch??

Friend: Yeah! I did it right beffore we both came and IT WAS AWESOME!!

Guy: Cool!! Good thing you didn't punch too hard because you can break your dick!!
