It's official! Urban Dictionary is a (semi-)reliable source, even used in courtrooms
Warning: some strong language ahead (NSFW)
Urban Dictionary is a crowdsourced resource to learn the meaning of slang words. While none of the words included were invented by Urban Dictionary, many (including some of the words below) have since been added to more traditional dictionaries; others may have been in these dictionaries first, but the peeps at Urban Dictionary just defined them better. We feel like these 100 are the words that everyone needs to know.
