Merriam-Webster, that duo in dictionaries, has acknowledged that people often use words that, well, aren't really words. Because of this, they have begun their online Open Dictionary, a place where W.N.s can submit words in from their lexicon and provide a definition.
What kind of words are these, you ask?
Try diabological: (adj) logical, but devilish or evil in concept
juxtalogue: (noun) a word pair in which one of the words is used exclusively or almost exclusively with the other word. Ex, halcyon days, scantilly clad.
twired (adj) the feeling one gets after drinking caffeine late at night.
