"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."
— Description[src]

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.[1]


Constant eye contact was required for this spell to be successful; if broken, the spell ceased to work.[1][2] 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, except powerful dark magic.[1]


This jinx was used by Quirinus Quirrell on Harry Potter's Nimbus 2000 in 1991, during a Quidditch match. It was an attempt to murder Harry for Lord Voldemort. No one in the stands detected Quirrell of using this jinx, except Professor Severus Snape, who attempted to save Harry with a counter-curse.[2] However, Snape's robes caught on fire when Hermione Granger used the Bluebell Flames on them, as she thought that Snape was causing the jinx. She knocked over Quirrell, thus breaking his eye contact, stopping the jinx.[1]
