Noun. An idiot from TJHSST and William and Mary who runs around in a bathrobe hitting things with his reinforced heavy duty umbrella. Capable of focusing his energy into a Super Bathrobe Ninja form.
Like other ninjas, he is a mammal and he does flip out and kill things, but purely in the name of good. Without the killing.
Rival to Zuki's Ninja Clan, and currently involved in an illicit affair with the rival clan's leader.

Wow, Bathrobe Ninja is really kicking ass and taking names today.
