A Sneaky Ninja is the act of defecating on an unaware preferably sleeping being. Anywhere on the abdomen, genitals, or face are perfect spots to secrete your waste on the unsuspecting victim. Sneaky Ninja’s are usually used as a form of revenge, although some find it rather arousing. It is best to perform a Sneaky Ninja after a hot Mexican meal, or a large dinner.

Thanksgiving can be the ideal day to perform a Sneaky Ninja; most people consume quite a large portion of food on this day, resulting in extra fecal production. Turkey also has an astounding effect to make people extra tired and fall into a deeper sleep. Both of these aspects together results in a rather satisfying Sneaky Ninja.

Some have been known to perform a Sneaky Ninja on homeless people when they can not find a public restroom fast enough. This is what we call a “Dire Sneaky Ninja” because the producer is in dire need for the relief of bowel movements. So much so that they needed to lay waste on the unsuspecting homeless.

All in all most find shittin’ on a bitch, whether for pleasure or pain, is truly a satisfying experience.
"Yeah I woke up with shit on my chest today. Turns out Jennifer Sneaky Ninjaed me for losing her CD!"

"After losing that card game and not paying up we Sneaky Ninja'd that bastard!"

"Damn! I gotta wash these sheets, that was potent Sneaky Ninja!"

"Shit! There are no bath rooms around! Oh thank god there is a hobo for me to Sneaky Ninja on."

"Yeah I was just sleepin' on the street and some little punk took a dump on my face! I heard it's called a Dire Sneaky Ninja"

"Hey isn't that Mike!? Let's Sneaky Ninja him for stealing Melissa from me!"
