Anti-Ninja 

Anyone who can beat a Ninja in a fight/wrestling/etc.

Anna beat Daniel in wrestling, and Dan is a ninja, therefore Anna is an Anti-Ninja

This is what the teachers at my school were.

Real Life Story
(Me climbing onto the roof and walking around)
Teacher: Excuse me!
Me: Huh?
Teacher: Get down from there this instant!
Everyone Watching: What an anti-ninja.
( Next week I'm in detention)
