It’s where two guys are in a pond and find a snapping turtle and don’t know which end is which but they both pull them out and see which one gets the poop chute and which one gets the clamp
Tennessee turtle turd clamper, Oh my God Jim did you see Jerry do that Tennessee Turtle turd clamper last night it snapped his dick off
When a woman has taken a fresh poop without wiping, and you proceed to put your dick in and out of her ass in a swift motion (like a turtle)
*thoughts from steven* "I wish Catherine would hurry up and get out of the bathroom so I can give her this Tennessee turtle....but what if she wipes? Ha, she better not wipe"
