"Harry had already attempted a few of the Prince's self-invented spells. There had been a hex that caused toenails to grow alarmingly fast (he had tried this on Crabbe in the corridor, with very entertaining results)..."
— Description of this hex[src]

This hex (incantation unknown) was used to cause the victim's toenails to grow at an alarmingly fast rate.[1]

History[]

This hex was invented by Severus Snape and recorded in his copy of Advanced Potion-Making during his school years at Hogwarts School of Witchcraft and Wizardry.[3] Therefore, it had not been approved by the British Ministry of Magic.[2]

It is unknown when Severus Snape invented this and many of his other spells, as according to Sirius Black "he knew more curses when he arrived at school than half the kids in seventh year".[4]

In 1996, Harry Potter used this hex on Vincent Crabbe in the corridor, with "very entertaining results".[1] Ron Weasley also recommended trying it on Cormac McLaggen.[5]
