If you're in public and have no escape route and know that the fart is coming on any second now, then your best bet is to slowly release it. Carefully and slowly unclench your butt cheeks, wiggle around a bit, and then let the fart slowly escape from your body. If you let it out all at once, it'll be more likely to make a loud noise. So this isn't the most ideal maneuver, but sometimes, you just know you have to fart, and you have no option but to make a loud noise or to cause a diversion when you know the time has come. Here are some things you can do:  Cough loudly Laugh loudly Drop a textbook Turn on the radio Set off a phone alarm This is the easiest way to fart and get away with it. If it's possible, then you should simply excuse yourself for a minute and then go and do your business. Here are the easiest things you can do:  Pretend to take a phone call Go "check something out" on the other side of the room Say you need some fresh air Say you want to wash your hands Use the bathroom

How would you rephrase that briefly using Vietnamese?
Xì hơi thật chậm. Tạo ra âm thanh lớn để át tiếng xì hơi. Lấy cớ đi ra chỗ khác.
