fumber
The fake phone number you give out when you don't want to give your real one.
This douche wanted me to give him my digits, I didn't want to be completely rude and immediately crush his dreams, so I just gave him a fumber.
Fumbered
The act of being overly fumber, such as in inhalation of too much of the sweet chung (marijuana) or drinking too much to the point where you put your shoes in the blender. This word comes from the ancient dictions of the Balfaic Ochungus who lives in Mount Ochungus.
Bro, last night I was so fumbered, I saw a flat bunger.
fumberous
to be insanely dubious
"Your choice of words are confusing me. Your acting a bit fumberous right now."
