Listen up, wordsmiths: The dictionary just got a whole lot more, uh, hip. In an effort to keep with the times — and possibly other slang-wielding competitors like Oxford English —Merriam-Webster just added more than 1,400 words to its Merriam-Webster Unabridged edition, and some of their choices just may surprise you.

Case in point? FOMO, for one. That’s riggggghhhttt, now no one human need have fear of missing out when it comes to knowing the popular slang term’s (a noun, according to the book) definition. Other popular abbrievs (pun intended!) that made the cut? TMI (that’s too much information, for the jargon impaired) and ICYMI (ya know, in case you missed it).

Unabbreviated yet unexpected picks include athleisure (thanks, Ivy Park), officially defined as “casual clothing to be worn both for exercising and for general use,” nomophobia (“fear of being without access to a working cell phone”), bit-coin (“ digital currency created for use in peer-to-peer online transactions”) and revenge porn (“sexually explicit pictures of a person posted online without that person’s consent, especially as a form of revenge or harassment”).

Well there you have it, grammar junkies! You’re officially clear to go nuts with these terms — and approximately 1,393 more just like them!
