Jacked Stiff
A Jack Stiff is someone who lives like a fool and is basically a walking death wish. They're so stupid, they might as well be dead already.
My neighbor is a Jack Stiff. He drives like a maniac and drinks all day. He's gonna die young.
My brother is a Jack Stiff. He fights every stranger and thinks he's invincible.
My friend is a Jack Stiff. He jacks off in public and then gets hit by a bus.
