Penis Ninja is the Ninja of the peen and is sometimes used to insult someone but mostly used as a reference for an awesome event that has happened.

It is also used as a random ninja attack phrase when trying to scare someone or when trying to invoke the spirit of the Penis Ninja"

"Justin Bieber's sucks ninja peen"

"Hey did you take my last Kit-Kat?"

Penis Ninja

An assassin who uses stealth and guile to assassinate a penis, often causing death to the owner of that penis. Scissors, knives, razors, and fire are typical weapons of a penis ninja. An historical example of a penis ninja would be the woman who killed Genghis Khan by slicing off his royal penis. Lorena Bobbitt is a more modern penis ninja of note, although her intended target managed to survive and was reunited with it's body.

I found out Jasmine carries a tanto knife in her purse. I hope she's not a penis ninja.
