San Clemente Sludge Sled
During anal sex doggie style, when the female begins to crap, or poke a turtle head, the male jams the crap back in with his penis.
"Lisa told me she had to deuce last night before sex. I was so horny I told her to wait. Unfortunately I had to give her the old San Clemente Sludge Sled to keep it in a little longer so I could cum."
