Beefy jock

The bully jock was a friend of Fred Jones who tripped Shaggy Rogers on the bus to school every day, saying it was "so easy." Fred disapproved, but he did nothing effective to stop it.

Scooby-Doo! The Mystery Begins
What really stopped the bully was when Scooby-Doo bit him on the angle in retaliation (Scooby was on the bus in disguise).
