I mean do I find it obnoxious and immature sometimes? Sure. But that’s more youth being youth, and also I’m guessing it’s a way to try to make their very scary reality a bit less intimidating. My generation said “knocked up” to refer to somebody getting pregnant when we were young. Also immature and disrespectful which is like… what young people do best. They’ll grow up, and more confident, and most will experience enough life that they’ll want to use more serious language. You know when I stopped using “knocked up”? The first time I had friends that had fertility problems or unwanted pregnancies. Those experiences made me grow up and start being more respectful.
