I'd be more than happy to specify:
"and kicked me for something as benign as something or another about their success in a particular game hinging on rng crits."
benign = harmless
something or another = some miscellaneous statement I made
ie, he kicked me because I made a relatively harmless statement. That statement consisted of me correlating his success in that game being reliant on his crit luck. I can't remember specifics, but I think it went back and forth once or twice, where he stated he can't choose when he gets random crits. I stated (paraphrasing), I know, hence the word "luck."
Very shortly after that, I get disconnected and a message stating "Kicked: (something here, can't remember specifics, but it was clear in that it was a human decision and not server)."
