Allow me to rephrase what I meant by a "non-word", as I doubted it would spark up any sort of controversy.

A word, in my book, is any continuous series of letters confined by punctuation or spaces. A real word is one that is found in dictionaries. I'd say that yes, "eoxlibnsdaienvlab" is, by the most strict definition, a word. But it's not a real word. It's never been used in conversation, unless one of you has (somehow) muttered it today or yesterday, it's probably never existed in a sentence until WW did the honor, and no dictionary would even think about accepting it, even under the definition of "a ridiculous series of letters". I guess it just depends on your personal definition of the word "word".
