Wiktionary

Volunteer-built word database

Wiktionary is a free, collaborative online dictionary project operated by the Wikimedia Foundation, the same organization behind Wikipedia.

Unlike traditional dictionaries compiled by professional lexicographers, Wiktionary allows anyone to contribute and edit entries, covering words from hundreds of languages with definitions, etymologies, pronunciations, and translations.

I looked up the slang term on Wiktionary since my regular dictionary didn't have it.
