Roommates are of poor quality. What is the experience of swearing?

I have a roommate who has very bad living habits and poor quality. You can say to grind your teeth, fart and snore, because after all, everyone has some bad habits, which is understandable. But his habit, I can't accept it. That is, playing games after midnight 12 o'clock, or even after 1 o'clock, and it is very loud. Yes, he is the king, and he will play the glory of the king there at twelve o'clock or even one o'clock every night! Every time I play my mobile phone loudly, I still shout here. Once I couldn't stand it, so I let him wear headphones, and people didn't listen to you at all. As a result, we almost fought. Really, it's not just me. Is that our whole dormitory can't stand him like this. But he went his own way, completely ignoring our feelings.
