An ass that you cannot see. According to the person with this ass, it's apparently there, but not visible to the naked eye. This is just an excuse for a woman with a really flat ass.

STEFFFF: maybe it was my ass
Finneh: What ass? OBRN!
STEFFFF: its there. =(
Finneh: So apparently you have a ninja ass.

Dirty Ninja

A variation of the Dirty Sanchez but for real ninjas. When conducting a Dirty Ninja the Ninja in question will take his penis out of his womans ass and wipe fecal matter all over her face leaving only the eyes visible. After you have accomplished this you must proudly proclaim out loud "Dirty Ninja" to be an offical Dirty Ninja.

WARNING: A Dirty Ninja is not to be taken lightly, loose peanuts or corn may cause skin lacerations or eye injuries
