An outrageously powerful slap delivered into the ear by the inside of one's bare palm. A loud slap is heard from across the room and the victim is usually left temporarily deaf, hence the name. The slap is preferably delivered after administering a droplet of spit into the palm and without the victim seeing it coming. It can be used as a verb in all tenses.

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.

Anatidaephobia is derived from the Greek word "anatidae", meaning ducks, geese or swans and "phobos" meaning fear.
