This website disgusts me and many others, judging by the positive reactions to negative definitions of Urban Dictionary. It is hideously innappropriate and does not discriminate in what race/religion/gender/etc it discriminates against. Every other definition--probably more like 9 out of 10 definitions--is foul and sex-related. I admit to using it sometimes to look up words I hear used, but still, when I continue to look up random words, as I inevitably do, I find myself being disgusted around every corner.
I just don't even have an example to give because I am so disgusted by Urban Dictionary.
