Brainrot zoomer language was pioneered by members of our generation, yet is cringe to us. Same with "XD :3 ><" and the generation before us. Stuff becomes cool because older people start it, only for younger people to embody it. "UwU" is a gift that we ought to respect (≧ω≦)
it was moderately post ironic for us, when we used it. It went from being a once in a while thing just to add some additional slang. To a post hyper irony period where the joke is that the words we used dont make any sense and have no meaning, therefore you can just do that with EVERY word.
