The Urban Dictionary is actually a crowd-sourced website that allows anyone to suggest a new word or a new explanation of an existing word. It is like a digital repository containing over 8 million definitions. It is also famous for being the vault of all kinds of modern slang, cultural expressions, adolescent humor and much more. Urban Dictionary was founded by a student of Computer Science, Aaron Peckham, in the year 1999. It was created to be a parody site of Dictionary.com. But today, Urban Dictionary is more than just a parody site – it attracts over 65 million visitors per month.
