It’s meme usage among kids. Anybody sharing/making “old fashioned memes” is a boomer. Anybody who is sharing obviously political memes (like political Pepe, not the feels one) is a boomer, any meme that’s unironic etc.
It’s the younger generation shaking off the meme “gatekeepers” – older gamers mostly.
If we have disagreement it’s ok. Gatekeping meaning is what we all do from time to time, me as much as everyone.
I just love watching meaning morph and change over time, ever since i learned of the “Great Vowel Shift” in linguistics.
