I bet there's news stories talking about how the finger guns meme is actually an act of silent protest or some such.
Came across a so-far hopefully untainted, different memetic phrase yesterday: "millenial grey".
The girl in her video [0] successfully identified that it is largely rooted in a 2023 media campaign. She then proceeded to feature two supposedly "completely average" friends of hers as definitely unbiased anchors, and held a community poll, also supposedly unbiased. Predictably, everyone knew what "millenial grey" was, and quickly agreed it was the worst thing ever.
She even made a fun little browser-based pixel art minigame where people could customize a room with a number of colorful options, and an extra bland rendition of "millenial grey". I especially appreciated the false implication that your choices in dressing up a pixel art room definitely translates to your taste in real-life house décor; just like watching gangbangs on pornhub means you'd be interested in taking part in one, of course.
Considering this was the very first time I've ever heard this phrase uttered, to see it being used as if it was something you learned after saying mum and dad as an infant, it was approximately the most living-in-a-bubble type thing I've ever laid my eyes upon. She somehow managed to socialize so perfectly tuned around this, she had absolutely zero chance of actually recognizing it for what she clocked otherwise immediately: a manufactured outrage over basically nothing.
But then I do also keep my own - so far, rather short - list of political dogwhistles, so maybe I'm just being uncharitable with my parallels.
