i've been on my phone/social/media/etc through the entire trend and this is the only time i've ever read the word 'delulu'; I had to look it up.
Might I suggest that tribe matters a lot in this context?
I don't listen to k-pop, I don't watch machinima, and I only knew 'tradwife' from the bullshit politics associated with the concept..
I think Cambridge called these too early. Maybe i'm old, and maybe i'm sheltered, but I never hear these words used in real life aside from a young nephew who was into the toilet thing, and he didn't so much use the word as just scream SKIBIDI while dancing around the room.
I'm fine with being old. Some trends you prefer to see sail away from you.
