The Candlebox effect is when an individual or group, usually in a theater or sports setting, gets up and starts dancing for no apparent reason. This phenomenon was witnessed during the alternative rock group, Candlebox, show at Celebrity Theater in Phoenix in 2014 , in which a lady was reported to have stood up and danced in her seat during the entire acoustic concert much to the dismay and amusement of other concert goers.

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.
