The Urban Dictionary is a lot like Wikipedia, it's written by the users. So it's not always reliable. You have to take it with a grain of salt. But then again, slang is usually written by the people who use it, so it's strangely appropriate. If a word is incorrectly defined in the Urban Dictionary wouldn't that mean that someone somewhere is simply using the word incorrectly and therefore making that term a newly defined slang term in itself?

Man, I need to get laid.

Besides, everyone knows that "Choda Boy" was the faithful sidekick to the greatest superhero ever... ORGASMO!!!
