Dictionary on fleek! It's official: The Kardashian-loved slang now has its own entry on Dictionary.com, which added 150 new words to their online word definition database.

Millennial favorites, like fleek, yaaas, feels, doge, and more, also made the cut for 2015. 

Acceptance of these words, largely used in slang, memes, and social media, is an indication of just how important those communities are. "This update continues to show how digital culture, in particular, affects our communication and ever-evolving language," Dictionary.com said in a statement on Nov. 10.

Aside from the already named additions, the online dictionary is also including facepalm, TBH, bestie, gender neutral identifier, Mx., shootie, IRL, respawn, and sapiosexual to their list of credible words and phrases.
