BAZINGA!

This, as many of you will know, is a taunting word used by Sheldon in The Big Bang Theory.  However, it has also entered the realm of zoology.  A species of bee was described in 2012.  It is found in Brazil and was deliberately named Euglossa bazinga after Sheldon's word.  It has also been used as the name of an Australian jellyfish, the Bazinga, discovered in 2013.
