Urban Dictionary is a crowdsourced English-language online dictionary specifically focused on slang words and phrases. It was founded in 1999 by Aaron Peckham. The site originally aimed to catalog slang or cultural terms that were not typically included in standard dictionaries but has since expanded to include definitions for any word, phrase, or event, often including multiple definitions and usage examples submitted and rated by users. It now serves as a popular repository for informal, slang, culturally specific, or newly coined language used primarily by younger generations and niche communities. Urban Dictionary has millions of definitions and attracts tens of millions of visitors monthly.
