How to fart in the dormitory to solve embarrassment?

If everyone is playing in the dormitory, such as playing cards and chess, and suddenly farts like thunder, you can make fun of yourself and make your roommate laugh it off. If you are reading in the dormitory, or have something to do, there is no need to worry so much. As long as the human digestive system works normally, there will be excretion. Although you regard fart as a "cloud", you will get used to it over time.
