A kloppenburg Surprise is when cut a hole in the bottom of a christmas present and set it in your lap while you stick your limp cock inside. Stuff tissue paper inside the box, covering your penis, and ask someone to open it. The victim will be forced to stick their hands inside the box and dig for your surprise.
Oh my gosh! All I got for Christmas was a Kloppenburg surprise!
