One might say "i know karate, i know kung fu, you mess with me, i mess with you!" To ward off unwanted attention from bullies. Mostly unsessful.
Also, a phrase used often by geeks trying to sound cool.

Puppets Doing Karate

It's that thing of when someone calls Miss Piggy fat, and she goes "Hiiii YA!"

New York's hottest club is OUNCE. Located in the middle of the East River, this place has everything: Cholos, puke-people, a sheepdog that looks like Bruce Valance, and an entire room of puppets doing karate.

Underwear Karate

This is when you are either feeling tired, are stoned, or are just feeling like doing "karate". This is a very broad term that can be used for anything ranging from a kid who thinks they are doing karate well saying a bunch of "hi-ya" this and "hi-ya" that until they eventually hurt somebody and their parent tells them to stop, to a professional karate master just feeling like doing karate in the hallway on their way to get coffee.

I saw my brother doing underwear karate in his room through a crack in his door.
