A Nut Gut is when an erect penis goes flaccid without releasing the goods which in return then makes the stomach/ gut painful.
Guy: Babe, don’t get me hard if you’re not about it
Girl: I’m sorry I just don’t feel like having sex right now
- Guy 10-20 minutes later with an upset stomach
Guy: Fuck Karen, I have a Nut Gut now. Thanks.
