"His broom gave a sudden, frightening lurch. For a split second, he thought he was going to fall. He gripped the broom tightly with both hands and knees. He'd never felt anything like that. It happened again. It was as though the broom was trying to buck him off."

This jinx (incantation unknown) was used to make broomsticks try to throw their riders off through a variety of means such as sudden lurches and violent swishing movements. Constant eye contact is required for this spell to be successful; if broken, the spell ceases to work.

It was likely an extremely powerful Dark spell, as Rubeus Hagrid stated that nothing but that could interfere with a broomstick, particularly a Nimbus 2000.
