A humorous word used in the dialogue of Marvel's 'Avengers Assemble' Movie. A portmanteau word (2 words combined together to make one word e.g. 'Belieber'=Believer+Bieber) 'Capsicle' is the word formed from the combination of Captain and Icicle. Tony Stark, (Iron Man) says this to Captain america during an argument:

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.
