Mabricio
Mabricio is super smart, but he can be a total pain in the butt. If you're his girlfriend, he'll try to make you the most popular girl in school. But if you're his sister, he'll drive you crazy with his video game rants.
He told his sister she was 'the worst' just because she didn't like his favorite game.
He tried to convince his girlfriend that his best friend was a 'total loser' just to impress her.
He screamed at his sister for 20 minutes because she wouldn't stop talking.
