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?!?!?!?!?"
Urban Black Country: Urban , had to get it out the dirt. Former Black ancestors of slavery. Country, what country. There's no question about it; America.
When you think of the most genius word or phrase ever, so genius that it can't possibly be already defined on urban dictionary. You hop on urban dictionary and excitedly put it in the search bar, when lo and behold, there's your word or phrase, definition and everything, already thought of by someone just a little more witty and clever than you.
Man, there's gotta be a term for that. It's like getting cock blocked. Heh. Dick blocked. HOLY SHIT, DUDE! URBAN DIC BLOCKED!
*looks it up real quick, reads the above entry*
