I have this social group, and there's a dude who's been getting out of line lately. I almost feel bullied. Don't know how to stand up to him. Face to face he would never dare to attack me the way he has virtually (but since we are in quarantine, we are in group calls). I need some verbal game to take this guy down. He's been really abusive and while he plays it down as "group banter" i am fed up and I don't want to become the group's punching bag. I need a way to answer to his shit tests. He has been attacking my physical appearance, specifically my beard, but crossing the line. Like "you look like a piece of shit". Not in a banter way, but in an aggressive way. Irl would beat him up (i never had the need to because irl he never pulls this shit, he wouldn't dare (he's a short guy, i'm much bigger than him). What do?
