ninjapoo 

a sneaky type of poo that quickly hides in the shadowy hole in the back of the toilet so that when the person who birthed that poo turns to check, it appears there is no poo whatsoever!
Belvedere Sampsonite discovered he ninjapoo in 1708 after refusing to believe that all his pushing and groaning had been for nothing.

Abe thought someone had stolen his turd but Francis said its probably a ninjapoo.

ninjapoo 

This is when you climb into a black bag, get someone to tie it up and the person in the bag takes a shit and has to see how long the can stay in there for.

I had a ninjapoo at a sex party and lasted 13mins 12secs

ninjaporn 

A delightfully pervy, geeky, disturbing, and quite blasphemous IRC chatroom where only the awesomest of people reside. Inhabitants are called 'Ninjapornians'.

"Oh god, I think I've been permanently scarred by that one Ninjapornian's links. Did you see the size of that thing? That's just not right!"

Ninjapotamus 

A ninjapotamus is half ninja & half hippo creature that lives in a triangular shaped Umi Sake house. He eats bananas and drinks Jaeger bombs. He fights crime on the streets of Seattle pulling all sorts of kung-fu moves. It should be noted that his kung-fu moves arnt all that smooth. That's the key to the ninjapotamus. Hes very clumsy but he thinks hes very slick.

Is it a bird?
Is it a plane?
NO! ITS A NINJAPOTAMUS!

ninjapocalypse

When the world ends because ninjas decide to take it over. So only ninjas and their slaves will live in the new world and all of us are either slaves (us strong ones) or killed. Anyone who puts up a fight thinking thy can defeat the ninjas will be mistaken. No armies could defeat ninjas.

The ninjapocalypse is upon us.
