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.

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!
