human wrecking ball

A wrecking ball is a very large steel ball that is used to knock down structures.

1. Someone who behaves in a reckless, destructive manner. If that new manager thinks he can just come in here like a human wrecking ball and shake up in whole department, he's got another think coming! That clumsy oaf ran through the store like a human wrecking ball and broke tons of my merchandise! If you don't keep an eye on your toddler, he'll run through Mass like a human wrecking ball.

2. Someone who uses their superior physical size and strength against opponents, as of an athlete. Their defensive line is made up of human wrecking balls, so good luck getting any penetration. Be careful, their top defenseman is a human wrecking ball who will definitely come after our smaller forwards. You can't just be a human wrecking ball without a game plan, or you'll spend the night in the penalty box.
