Are there any internet memes or flavour-of-the-month words/terms that really grind your gears?

For me there's a particular three that really annoy me.

1) Waifu.
Original context simply referred to a female anime character to which person might develop an unhealthy obsession, and it was still a pretty obscure term outside of Japan or dedicated anime communities - but now it's absolutely EVERYWHERE. It's become the massive go-to word to describe a character in games, literature, fiction or art that you like. You hear it constantly used by game reviewers now to describe the companion rosta for any RPG on the market. I've no idea why it annoys me, it just does. 

2) Butthurt
I fekking despise this term. Fortunately it seems to be on the way out, it's very much last-season's meme. Thank God!

3) The 'C word'
I suffer from an illogical superstition that naming evil things like this will somehow cause them to manifest. No it makes no sense at all, but there it is. Having recently lost a close friend and several relatives to the 'C-word' seeing it constantly used as a flavour-of-the-month meme (usually by younger people) to describe anything they don't like "This game is C*****", makes me cringe. I can't even finish reading the thread when I see it.

4) ...and speaking of 'cringe'....
This is another term that really grinds my gears: "That's just cringe".
Once again I have no idea why this annoys me so much, it just does. Maybe it's the grammatical murder, or it's sheer prevalence, who can say? It just annoys me for some reason.
