I'm not exactly sure of what specifically he said that pissed you off this much, but I'm guessing it's just shitposting. Everyone gives everyone else shit, including you, it's just for the lulz though. And when you're bantering then someone demands you emergency brake and be serious, it's tough when you're a dickhead. It's not at your expense, if he genuinely thought badly of you he'd of cranked it to 11 by now tbh 🤷🏻♂️
