The sound you make when you're riding a rollercoaster and giving head, while he proceeds to cum in your mouth while going down a hill of the rollecoaster!

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.
