A J-Turd is an uncommon occurence that happens whilst dropping a deuce. What happens is, your turd exits the anus, also known as the turd cutter, and forms a "J" shape that then curves up and touches the bottom of your genetalia (i.e Scrotum or Labia) This can lead to stinky genetalia and some turd spots. Other common side-effects are corn or peanuts stuck in your pubic hair.
Kolton: Dude, I was at home yesterday dropping a huge dump from all that McDonald's I ate and I let out a nasty J-Turd. I still haven't gotten it all out from my bush!
Isaac: Wow dude, that's sick. Don't talk to me anymore.
