Gr16 is essentially gr8 (great) but used when something is too great for a simple 'gr8' to be used. It is double the power of a regular gr8, and when something is even gr8r than gr16, one can multiply the number by a multiple of eight. (example: gr32)

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.
