jackbat
A halfwit who acts like a total idiot and still thinks they're cool.
My cousin tried to start a band and called it 'The Jackbatz.' No one asked why.
He walked into a restaurant and yelled, 'I'm the king of this place!' The waiter said, 'You're the king of dumb.'
He tried to propose to his dog. The dog just looked at him like he was a piece of meat.
