Hail No - A metal guy's way of saying 'hello', it's like they're all i

A metal guy's way of saying 'hello', it's like they're all in a cult and they scream it at each other like f***ing lunatics.

"Hail no!", during a metal concert, screaming at the top of his lungs

"Hail no!", while wearing a f***ing cape

"Hail no!", while eating a whole pizza and yelling at his friend
