omg im literally crying!!”
don't forget the strong use of hyperbole in the English language and especially American culture. If something wasn't "amazing" or "awesome" but merely "good" most people there would think it was actually bad or average at best. Even the word 'literally' itself isn't to be taken literal.
Just think of all the strong metaphors like "I'm dying" or "the hill [someone's willing] to die on".
American English just has it with superlatives and extreme imagary.
So most people when they say they're crying mean that's very emotional for them, but they most likely don't cry in a literal sense.
And if you mean Youtubers, we'll they get money for reactions/interactions. so they themselves go with it head on. Just look at all those exaggerated thumbnails people doing weird faces on. That's what sells. That's how you get clicks. Works perfectly in harmony with a modern society going in hard for extremes and a language that keeps up
amazingly well with that.
