Look, we're not trying to be fuddy-duddies about this whole thing, but you have to draw a line somewhere and the English language is something that we happen to care about quite a bit.
A number of words have just been added to Dictionary.com that make us facepalm in disgust at… oh, wait. Yeah, 'facepalm' (the gesture of placing the palm of one’s hand across the face, as to express embarrassment, frustration, disbelief, etc. (often used as an interjection) was one of them. Bah.
Recent slang like 'Yaaas' (Slang. Yes! (used as a strong expression of excitement, approval, agreement, etc.) 'drunk text' (to send a text message to someone while intoxicated), 'fleek' (Slang. flawlessly styled, groomed, etc.) and 'kk' (Informal. (used in text messages and other digital communications) okay; OK) have all been added, too, meaning that if you decide to invent a random made-up word or phrase and circulate it around the Internet, there's every chance that you could make your mark on the English language, eventually.
There are even a few meme-related words included amongst the new additions, like 'Doge' (an Internet fad or meme typified by an image of a dog of the Shiba Inu breed accompanied by very short phrases that humorously represent the dog’s imagined thoughts and use the wrong modifiers or shortened word forms, as “such dignified” or “amaze.”)
Dictionary.com is not quite the OED, true - but where do we draw the line? I mean, 'fleek'? Really, what would Shakespeare say?
