I'll slam ya uncle - You say you're so good that you can beat someone and their u

You say you're so good that you can beat someone and their uncle, like they’re both weak and you’re the king of the block.

You're not even worth my time, I'll slam ya uncle and he'll be too scared to fight back.

I'll slam ya uncle and then I'll laugh at him.

I'll slam ya uncle so hard, he'll go home and tell his wife he lost to a kid.
