How do you scream?

Like I get the push more air through your mouth and get louder but my voice never breaks. I just get louder and louder and louder until I can't get louder anymore.

One time a friend of mine was a half a block away in the wrong direction and I screamed their name and they jumped because they said it sounded like I was right behind them talking in my normal voice just very loudly.

But then I listen to singers and they get that raw raspy edge to their voice and my voice doesn't do that.

How do you do that?
