1. It's spelled this way because "Urban Dictionary" does not allow itself to be defined.
2. An idiotic website, created by people who have nothing else to do except encourage cretins to make up stupid words.
3. A website that might have a lawsuit against them, unless they remove slanderous entries about people.
"That garbage website did an 'ubran dictionary' and disappeared".
You spelled it incorrectly. It's Urban Dictionary.
Since you're a moron, you should probably learn how to spell.
You just looked up "Ubran Dictionary" because you're either stoned, drunk, or just a bad speller.
