"Oh, I had no idea that was black/queer slang" and "In fairness a lot of is just seeing a word and not knowing what it means".
Like y'all are on the internet. If I see slang I don't know and can't suss out the meaning of, it takes 10 seconds, maybe less, to google "____ slang" and get exactly what I need to know. This is literally how language evolves and grows and just because it's sped up doesn't make it bad, you just need to stop being so rigid. Your way of talking definitely changes just by being online and you're only complaining now because it's clearly non-white or non-cishet culture making you uncomfortable.
