"Yeah, size is no guarantee of power ... Look at Ginny.... You've never been on the receiving end of one of her Bat-Bogey Hexes, have you?"
-- George Weasley (OP6)
The infamous Bat-Bogey Hex engorges an opponent’s “bogies” inside their nose to bat-size, gives them wings, and sets them to attacking his or her face.
History and Notes
The spell was created by Miranda Goshawk, in the late eighteenth or early nineteenth century. Miranda used it on her sisters to great effect, getting them to return borrowed clothes, keep out of her room, and be quiet when Miranda was doing homework.
