ninjacow 

An intense bovine version of a ninja, that nobody expects.

Right when the bad guy is about to mug the farmer, and burn down the farm, the ninjacow strikes, and completely destroys the bad guy, before returning to it's herd.

ninjacore 

the gayest thing a person can do in a moshpit. the "art" of ninjacore is basically doing ninja-like moves, such as spin kicks and spinning fists in an effort to make space for themselves in the pit. looks as gay as it is.

dude, this ninjacore kid started punching me in the trivium moshpit last friday so i knocked the cunt out!

Ninja Cow 

An asshole and bastard. Many have tried to combine the two and create the "Basshole", but that is simply silly.

You are such a Ninja Cow, Nova!

Ninjacore 

A form of the word Ninja Yes.

"Dude, that's a sweet bike."
"Yeah, totally ninjacore."
