Jackass Rednecks
They are the kind of people who think your mom is a joke and they'll laugh at you for no reason. They also think they're the kings of the world and they'll try to prove it by yelling at you.
You said 'hi' to them and they yelled, 'You're gonna die, you idiot!' and then threw a soda can at your head.
You walked into a store and they said, 'We're gonna kill you!' and then started a fight with the clerk.
You saw them on a dirt bike, screaming at a chicken like it owed them money.
