The ridiculous, utterly retarded notion or idea that your Urban Dictionary submission will ever, ever make it to the front page.
Jack: Hey, look, I just submitted something that I just know is REALLY funny that EVERYONE will love. If it doesn't get to the front page, then all the moderators of UrbanDictionary must be fucked up in the head!
The next day, looking at your word on Urban Dictionary (fervently thumbing it up, of course, in a futile attempt to get it noticed)
Jack: Fuck. I'm not funny at all. I hate myself. How did I ever hope for this entry to ever get anywhere and be anything else other than a file stealing server space from the good people of UrbanDictionary.com?
