You’ve ADHD and are Cartman’s best friend and know each other from childhood. Cartman/Erick knows people talk behind your back but you don’t know. Erick beats that sort people sometimes up to protect you from the shadows

Don’t you ever talk about him that way! Erick says, talking about you while beating someone up About who? You ask Uhh.. about my cat. Erick says as an excuse, he knows you can be pretty sensitive with your feelings so he never tells you when he beats someone up for you
