Coinage

Like its predecessor, the Simpsons, Futurama's writers and voice actors are constantly inventing new words.

Overview
The words said on Futurama don't always exist in a standard dictionary. Several words have been invented by the writers and ad-libbed by the actors, creating these words for us:

A

 * Axe :inquire, question; derived from the old english "ask." Ironically, this is actually a step backwards, as "axe" was the original pronunciation. Alternate spelling: Ax

M

 * Meatbag :A term referring to Humans (or organic creatures in general), may be a racial slur.
