Urban Dictionary does not provide any service, but has an online store that sells calendars, mugs, print editions, T-shirts and phone cases. It is an online dictionary that features user-submitted definitions for common slang words and phrases.
Aaron Peckham created the Urban Dictionary website in 1999 while studying computer science at California Polytechnic State University. Anyone can submit slang terms and their definitions to the site without registering for an account. Urban Dictionary has volunteer editors who must approve user submissions before publishing. Editors reject ads, nonsense content and sexual violence content submitted to the site. The website introduced its store in 2009 to sell custom products.
