John O

An autistic little fuck who thinks he's the shit but really is a little pussy who plays hula-hoop golf on his free time. John won the BE Award in elementary school (a reward given to absolute fucking retards). His sister is honestly the hottest fucking girl on the planet and I would fuck her brains out every single day of the week

What's the matter with that kid over there, and who's the hot girl next to him?
Him? Oh, that's John O, and that's his banging sister next to him.

John O’Neill

A worthless waste of oxygen who wastes everyone’s time and energy. He is nothing but a burden to everyone around him. He contaminants the dirt he walks on. The true definition of human filth.

“John O’Neill is a worthless pile of shit.”
