From Bzooty to Whiskeyclone (and yes, Bender, Odelay), it includes all the crazy words Beck probably uses in his songs that don't really exist but sorta do.
Bender: I could write a song, and using real words, not "odelay."
Beck's head: Odelay IS a word! Check the Becktionary!

Get the Becktionary mug.
Introduced in Futurama, the Becktionary defines all things Beck that are ambiguous.
WTF is a devil's haircut? Also, WTF is Odelay?

On Futurama, when Leela raised the question of whether or not odelay is really a word, Beck suggested that she check her becktionary; this is a dictionary of words that Beck has made up or given new definitions to, presumably. These include: odelay, sea change, devil's haircut, bizness, sexx, etc.
