How do you scream please :P (fry screaming would be great)?

Sorry to burst your bubble, but it is near impossible to scream like Mitch. He got his signature scream because he got some sickness (Bronchitis I think?) and then decided to practice his vocals despite the sickness. It ended up "damaging" his vocal chords, but ended up getting a bad *** scream because of it. About your question, I can't really answer it. The only advice I can think of is to get some mucous caught in your throat (Don't swallow your spit) Then use that mucous to create the fry scream sound. But don't let people tell you to inward/inhale scream. It doesn't sound good, and it's not very good for you.
