Sometimes the English Language Makes Me Sad

Is it necessary to include memes as official parts of the English language?  I mean, I know that the language changes and evolves, but do we really need "mansplain" as a word?

For those that aren't aware, the Oxford English Dictionary (the closest thing our language has to a presiding body) recently published new words that will now be included in their official dictionary.  Some words or phrases make perfect sense, like "Deep Web" and "octocoptor" since they describe actual things and are not simply a form of slang.  I'll even go for "tech-savvy" and "douchebag" since those words have each existed for well over a decade, so even if they're just slang words, they're slang words that everyone knows.

But "YOLO?"  That acronym didn't exist until three years ago, even if the phrase its abbreviating has been around for much longer.  And "cray" and "adorbs" are just really dumb abbreviations and portmanteaus like "listicle" and the aforementioned "mansplain" are, well, portmanteaus, so they shouldn't be official words.

Some of these words ("YOLO" in particular) seem like the OED is jumping the gun a bit.  Do you remember the Spice Girls' big hit "Wannabe" from the 90s?  It had a word in the chorus "zigazig-ha" that was utter nonsense.  Well, the Spice Girls were such a phenomenon that "zigazig-ha" was added to the OED.  I haven't heard anyone say that word.  Ever.  Now, the OED is a British publication and the Spice Girls were a British musical group, so maybe that word lasted longer in England, but I can't imagine it's still in use today.  It seemed like a dumb inclusion back then just like some of the new words now.

And before anyone brings it up, yes, I know that dictionaries act as a kind of historical document of language - I really enjoy looking up archaic meanings to common words - but, again, some of these words just seem like old, out of touch lexicographers are trying to prove that they're still cool and hip and are over-compensating.  Or maybe with the internet, English is evolving faster than I'm comfortable with and I'm just an old man that refuses that get with the times.

Now get off my lawn!
