rapgenius.com 

a website trying to do what urbandictionary already did

its kind of too late too
theres too much information on slang on the internet even without this site

Is the website rapgenius.com better than urbandictionary?

i doubt it because urbandictionary has had a ten year head start

but

As long as it furthers education i don't mind........
