A guy says it when he’s about to punch your lights out. It's not a promise, it's a threat. And it’s coming from someone who smells like a trash can.

I'll tell you what mate, I'm going to punch you until your face looks like a boiled egg.

I'll tell you what mate, I've been waiting for this all day.

I'll tell you what mate, I'm not going to stop until you're on the floor.
