Words 'ICYMI' and 'hella' have officially made it to the dictionary!

Washington D.C.: Merriam-Webster has updated the "unabridged" version of its comprehensive dictionary this week, adding some very of-the-moment words.

Some of the highlights include 'ICYMI' (in case you missed it), 'Bitcoin,' 'dox,' 'FOMO' (fear of missing out), 'TMI' (too much information) and 'nomophobia' (the fear of being without a working mobile phone).

According to TechCrunch, Merriam-Webster says they have added over 1,400 words including 'athleisure' (think: Ivy Park), 'revenge porn' and ' hella.'

Merriam-Webster's website says, "The new entries and senses offer a kind of snapshot of how exactly our language expands. It doesn't happen quickly-we monitored many of these words for years before they'd met our criteria for entry-and it's pushed by various fields and endeavors."

Others include 'wacky tobacky' (as in that phrase our parents use to describe marijuana) and 'microbead.'
