Like
nowhere, man!
Lacking any
coordinates in
space-time.
Not present on the
material plane.
The opposite of
ubiquitous.
I learned this word yesterday from my Page-A-Day calendar.
I thought this was one of those
fake words and broken definitions in dictionaries,
so I did a web search. Most of the hits were to pr0n sites
which included exotic words as search engine traps.
One site offered me the chance to "Bid on nullibiquitous on eBay",
but eBay told me "Sorry, we couldn't find any items for nullibiquitous".
That makes sense, since any item found there could not be
nullibiquitous, by definition.
