Presumably bites anyone who tries to drink out of it on the nose
A Nose-Biting Teacup is presumably an ordinary-looking teacup that has been jinxed to bite the nose of anyone who tries to drink out of it. Ron Weasley and Harry Potter each bought one at Zonko's Joke Shop on a trip to Hogsmeade in 1994.
