crusty bell flake
An extremely rare phenomena where a crust, usually composed of semen and fermented pus, develops on the tip of the bell creating a nasty smell and results in horrendous blistering...can only be treated by tickling the crust with the feather of a one-eyed yak thus causing it to turn into a mollusc which can then be removed using a ping pong paddle forged from the anal hair of an arabian horse.
See that Oliver guy? He had a nasty case of crusty bell flake...
