Another word for word. Not a homophone, as a homophone is something pronounced the same but has a different meaning.

Guy2: Whirrrrrrrrred!
Guy2: Whirrrrrrrrred!
Whirred
Whirred - Homophone of word. Used as an alternate spelling of 'word,' but indistinguishable in speech. Used primarily among the more nerdy groups as a means of trying to appear hip but still retain acceptance among fellow nerds. Can be used in place of 'word' in any phrase involving that word.
