Turtle Dip
Tea-bagging someone with a turd hanging half-way out of your asshole. Preferably, the recipient will be blind-folded or closing their eyes to keep them in suspense over whether they are about to get the ballsack or the shit with every successive dip.
"I gave your mother the turtle dip, not because she is such a whore but because I thought it would make her stop trying to fuck me."
Turtle-dipping
Where you rub your dick in turtle food and let a turtle eat it off of the penis
