The Dirty Patrick

When a transvestite bends over to indicate it is ready to mate. The transvestite then lowers its pants and under garments to reveal a morphed mussy and anus to reveal a purple butthole.

When you use a starfish as a dildo and then feed it to someone.

Also know as "The Raging Starfish," occurs when five men simultaneously penetrate a single man or woman anally. After the act has been completed and the men withdraw their penises, the anus resembles a stretchy starfish.
