(N.) The control Center for this website where new definitions are decided wheteher they enter in, and where other definitions are decided whether to be deleted or not. Who knows who it's run by.
Because of the Urban Dictionary Quality Control, most of my words don't make it the next day, or get deleted.
Noun: this is the sad condition during which you think of a slang term, the meaning of which escapes you, but you are riding in the car, lost in space, or engaged in a sexual act, and therefore can't access a computer... by the time you are at said computer, the term has fled from your feeble memory.
as in " I wonder what the hell "roflcopter" means... when I get to work, I'll UD it..." 5 minutes later... "Dammit, I have Urban Dictionary Block... WHAT THE HELL WAS I GOING TO LOOK UP?!?!?!?!?"
