E.O.O.
E. O. O. is the guy who got ditched but still acts like he's the king of the world. He's got no money, no brain, but he's got a ton of attitude.
'He texts me at 3 a. m. like he's the boss of me.'
'He thinks he's still cool just because he used to be married to me.'
'He got fired again and still thinks he's the best thing since sliced bread.'
