Two bands or musicians duking it out too see who is the best musician out of the two.

Looks like it's going to be a rock off between the Asskissers and the Alkatoids to see whos the better band.

I challenge you to a rock off

rock off 

When two (or more) people use the game Paper Scissors Rock to decide the ownership of a certain item. Mostly used in Australia. Spoken as "I'll rock you off for..."

Person 1 - "I'll rock you off for that burger." (or, "Let's have a rock off for your burger!")
Person 2 - "Ok, let's go!"
Person 1 and 2 - "1...2...3!"
Person 2 - "Damn, I chose scissors when you chose rock!"
Person 1 - "Haha, rock always wins. Thanks for the burger!"
