turtle hurdle
When a man is having sex with a woman from behind and, while about to ejaculate, sees the tip of a stool (the turtle) poking from her anus. He quickly pulls out and launches his semen over the poop onto her back (the hurdle).
I was banging my woman from behind and was about to nut when she started to shit herself. I quickly pulled out and did a Turtle Hurdle onto her Tramp Stamp. That shit was nasty but a guy’s gotta blow sometimes.
