Jabari Parker is so metal he's headbutting the rim during dunks

METAL!

Please dunk responsibly.

We're serious. Especially if you possess tremendous hops like Bucks forward Jabari Parker. He got so high that he literally hit his head on the rim.

Maybe this is just a way for Parker to innovate the slam dunk contest for the upcoming All-Star weekend in New Orleans. Yeah, every participant can dunk but who is metal enough to start headbutting the rim, and then deliver a monster slam? We don't know for sure but Parker seems up for the challenge.

He might be on to something here.
