When a man is banging his girl from behind and his johnson slips out in mid-motion. At this point he jams it in her ass hole and she humps her back up like a turtle shell. You can only do this if you accidentally slip out so she will least expect it.
I was banging my old lady last night and gave her a turtle back when she wasn't expecting it. I then gave her a Donky punch and finished off with a chili dog before she woke-up.
