Well, this is one of the most interesting websites on the Internet! This site has the world's most complete collection of slangs and is constantly being updated by users with new slangs. All the slang submissions are vetted by editors to ensure the quality and accuracy of the slang. To date, there are over 4 million slangs definitions listed by Urban Dictionary. However, some of the quality of the definitions seemed to be rather poor. And probably due to the huge number of defintions, it can get rather confusing as well.
