Just like the words you'd traditionally find in the dictionary, there are so many slang words that not only have synonyms, but antonyms as well!
For example: have you ever noticed that someone can't be thirsty while also having swag? Or that netflix and chill and spotify and sidehug sound similar but describe either rejecting someone or inviting them over?
Thanks to sites like Twitter and Instagram, where slang abounds, it's easy to find exactly what you need to say ... or the opposite of it.
Or on sites like this one, because we'll just keep building these lists for you 😉.
