Dothwelmer

Sexual trick. While the female is giving head to the male, he pushes her head down balls deep. He holds it there no matter how hard she fights, until she passes out. Once unconscious, he pisses on her face, shits in her mouth, and bounces. Leaving her with a nasty mess and (if well planned) a hefty hotel bill. Works great on (soon to be) ex-girlfriends.
