When you "return" your books back to Chegg rentals at the end of the college semester, but instead of books you fill the box with feces and rig it with a small timer that triggers when the tape is ripped open on the box so shit explodes in a motha' fuckas face!

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.
