labonza - A threat from Legs on The Simpsons. He says it. He beats you

A threat from Legs on The Simpsons. He says it. He beats you up. You remember it.

Legs said labonza. I now have a black eye and a bruise for my sins.

Labonza! That's not a threat. That's a death sentence.

Legs said labonza. I now live in fear of a belly punch.
