In the 1993–1994 school year at Hogwarts School of Witchcraft and Wizardry, Hermione Granger learnt this spell from a spellbook, which she had brought from Fred and George Weasley in their shop on the sixth floor of Hogwarts Castle.
From English "snuffle", probably compared to sniffling mouse, with the -fors suffix attached.
