what is a traunch burger?

I thought it was something you treat yourself to when some extra money comes in, like an expensive outfit or a spa day or something.

Traunch:

To push a friend in the back when he is not expecting it or is extremely vulnerable, especially when urinating.

“Ohh man JonO! You traunched me while I was peeing and now I peed all over myself!”

Not sure but.. UrbanDictionary says:

A raunchy naunchy burger.

“Traunch burgers taste good on the hole.”
