My roommate farted in the dormitory, framed me and gave me an insulting nickname, Fart King, what should I do?

Since you are a roommate, it is not easy to turn against each other. We live under the same roof. However, he is really not a man with a conscience. You can hit him back, "I am the king of fart, you are the king of stinky ass, and the two kings are family." Such people have low quality and can't make friends. From now on, keep your distance from him, neither too close nor too hot.
