The worst part is the look in his eyes. You can just see his brain stop working, like it just can't process words anymore. He goes into some kind of zombie-like state, he just repeats what they say if they're not muted e.g the Friday the 13th playthrough "yes that's right I masturbate in front of kids". And when muted or leaving the game his brain suddenly revives and he starts throwing out mundane stuff "what a morahn, just a brain-dead morahn dood."
When you can't even have friendly bants with the woman you're supposed to love something is genuinely mentally/emotionally wrong. Not even as an insult.
