How to Fry scream for hard rock vocals

Classically trained singers will tell you that screaming is the worst thing you can ever do to your vocal chords, but if you're into singing/screaming heavy metal or rock then it's necessary to know how to scream with minimal damage.

The correct way to scream is a technique called fry screaming, in which you control your vocal exhale using diaphragmatic breathing. Vocal fry is the noise you make when your vocal chords vibrate slowly.
