Wibble?

What it probably doesn't mean

The Jargon Lexicon has a definition, but here are some other definitions for no reason whatsoever:

• Weird and Interesting Beings Begotten of Lemming Experimentation
• Westlife Incessantly Bleat Boring Lyrics Endlessly
• Winking In Big Bathrooms Leverages Excitement
• Wibble Is Being Blatantly Lewd Excessively
• Would Intense Blowing Beget Loose Endeavours...
• World's Idiot Brethren Begin Long Excursion
• What If Boredom Begets Lunatic Explanations?
• Which Idiot Began (these) Boringly Long Expansions
