I rub you - When somebody says I rub you, they are telling you they are

When somebody says I rub you, they are telling you they are going to rub you until you scream like a baby.

I rub you, kid. You're gonna wish you were still in the womb.

You better run, or I'll rub you till your skin comes off.

I rub you? That's not a threat. That's a promise.
