Watch Sean O’Malley hilariously kick fan in the butt in Japan

MMA fans certainly are different than most sports fans, which is something former UFC bantamweight champion Sean O’Malley understands now more than ever.

The star 135-pound competitor is currently in Japan for Tuesday’s RIZIN: Decade event, and took part in a fan meet-and-great days before the annual event. “Sugar” was asked by a fan to kick him in the posterior during the session, and O’Malley delivered a thudding kick that sent the man dropping to the floor.
