Cockney rhyming slang -- a butcher's hook, rhymes with look. The slang gets trickey in use as it is usually truncated. Apples and pears becomes apples, but refers to stairs.

Anatidaephobia is defined as a pervasive, irrational fear that one is being watched by a duck. The anatidaephobic individual fears that no matter where they are or what they are doing, a duck watches.
