Yaaas! Dictionary.com introduced more than 150 new words to its website on Tuesday (Nov. 10), legitimizing a slew of millennial-approved words and phrases you probably already use on the reg.

There are the obvious acronyms like IRL (in real life) and TBH (to be honest), but plenty of other surprising additions, like “matchy-matchy” (having colors or patterns that match or harmonize too closely) and even “doge.” Much meaning, very definition!
