Quote:TULSA, Okla. — In one video, a fan at a youth soccer game bellows profanities and violently kicks a ball that slams into a teenage referee standing nearby. She disagreed with a penalty called.

Another captures parents at a youth basketball game charging the court to hurl punches at the referee. And yet another shows parents berating game officials as they walk to their cars after a soccer game. The players were 8-year-olds.

The videos were posted on a Facebook page, Offside, created in frustration by an Oklahoma youth soccer referee, Brian Barlow, who offers a $100 bounty for each clip in order to shame the rising tide of unruly parents and spectators at youth sports events.
