What is the English term of utot?

Answer 1

utot is the expulsion through the rectum of a mixture of gases that are byproducts of the digestion process of mammals and other animals. The mixture of gases is known as flatus in medspeak, informally as a fart, or simply (in American English) gas, and is expelled from the rectum in a process colloquially referred to as "passing gas", "breaking wind" or "farting". Flatus is brought to the rectum by the same peristaltic process which causes feces to descend from the large intestine. The noises commonly associated with flatulence are caused by the vibration of the anal sphincter, and occasionally by the closed buttocks.
