A person who thinks they're the king of the world and acts like everyone else is beneath them.
I saw Hackliachiously at the mall. He yelled at the cashier for not giving him enough change.
My friend’s cousin is Hackliachiously. He posted a selfie in a toilet stall and called it a 'vibe check.'
Hackliachiously walked into a restaurant and told the waiter he was there to 'dominate the lunch rush.'
