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." Alternate spelling: Ax

M

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

R
Coined by: Hermes Conrad (2ACV06)
 * Rage Dump :An expression meaning that someone needs to either vent their frustrations or possibly relax. "Take a rage dump" may be analogous to "chill out".

S
Coined by: David X. Cohen, when explaining why he chose an "X" as his new middle initial.
 * Science-Fictiony :Of or relating to science-fiction.

Coined by: An unnamed old woman in the Last Curtain home. (3ACV08)
 * Scribble-Di-Gook :A contemptuous word for chickenscratch or written gibberish.
