look up any word, like sex:
When you have to shit so bad that you can feel a turd breaking the surface only for you to pull it back in, as if your ass is playing yo-yo with a shit.
Guy 1: Dude, we gotta stop soon.
Guy 2: Nah man, you can make it.
Guy 1: No, seriously. I've been playing yo-yo with a turd for the last ten miles. It's about time to walk the dog if you know what I'm saying.
