California word for TOUGH ...A bad ass MARINE or someone or something that is extremely TOUGH.Whom everything they do is to the extreme in manlyness. There is nothing tougher than a KEITH JACKSON!

Just give it a Keith Jackson, so that we know that it wont break!
They would probably make Keith Jackson toilet paper,but they can't because it wouldn't take SHIT from anyone.
