1. A website where douchebags come to when they are bored and post completely useless definitions. Most of the definitions they post have to do with sex/sexual acts. Definitions for words like blockhead, dentist, and other words that have nothing to do with sex.

2. Don't mistake these idiots with the people who post real definitions that actually help/inform people in some way.
Idiot: "Heh heh heh I know what blockhead means and it be naughty." >=D "Ima post it on urbandictionary."

Normal Person: "...People like you are a waste of our precious, precious oxygen."

Get a urbandictionary mug for your father-in-law Paul.
A website that has started as a briliant slang dictionary, but has just become the breeding ground for newbies who think it's a message board. It is now also used to define names, which isn't allowed, and to make fun of people.
urbandictionary used to be cool, but idiots messed it up.

Get a urbandictionary mug for your daughter-in-law Beatrix.
A website that contributes to the harassment of innocent people. When someone tries to remove a definition, even though urban dictionary claims that you can by clicking the remove button, a stupid message displays stating "this definition is way too popular." When someone tries to contact urban dictionary, they ignore all messages.
