Quidditch

Kwiid-itch, n. 1. Fictional Sport in the 'Harry Potter' novels involving bats, balls, brooms and C.G.I. effects - no doubt to be frowned upon when some daft bugger emulates it and falls to his/her doom on discovering they can't really fly. 2. The type of sneeze that starts in the nostrils, causing one to clamp one's teeth and close the mouth, resulting in sneezing a large clod of snot into one's hand that's in such a vast amount that it can't be wiped onto one's clothing discreetly.
