Type: Curse/Jinx

Pronunciation: Fur-nun-cyoo-lus

Use: To make a person break out in boils or pimples

Magic Moment: In Goblet of Fire, Harry jinxes Vincent Crabbe with this spell while George Weasley simultaneously hit him with a Jelly-Legs Jinx. The combination caused small tentacles to sprout on Crabbe's face.

Notes: While George Weasley refers to this spell as the Furnunculus Curse, Pottermore describes the same incantation as the Pimple Jinx.
