Dude2: Wow totally Decrapitated
When you have a turtle head pertruding out of your anus and you clench the anus hole and the turtle head falls off. Commonly known as the decapitated turtle.
Holy SHIT, my turtle head fell off in my pants and has left thick skids oh damn. Stupid decapitated turtle, shouldnt clench my anus when so excited.
I see why that motherfucker is dead, his head is laying way the fuck over there, about 10 feet from the rest of his body. That was a bad case of somebody getting decapitated, the doctor won't be able to fix him up.
When one is 'prairie doggin it' and clinches his or her rectum at a most inopportune time, resulting in a small turd being cut from the larger mass of shit completely or partially as a dingle-berry.
"Decapitate the Dog"
