High Five Gone Wrong

He wasn't expecting that this would be the result of standing at the edge of a motocross jump.
From the licensor:
"My cousin races pro motocross, he told me to stand on the edge of the jump. He said give him a high five and take a selfie in mid air. Ended up getting hit in the back of the head. I got head trauma, bruising and swelling of my head, and my arm was pretty ripped up."
