"FART" can stand for: Frequency Actuated Rectal Tremor.
Farting, also known as flatulence, is the act of passing intestinal gas from the anus.
Intestinal gas comes from several sources: air we swallow, gas that seeps into our intestines from our blood, gas produced by chemical reactions in our guts, and gas produced by bacteria living in our guts.
Burps are not farts that come out your mouth. They have to do with your stomach.
Why Do Farts Smell?
The smell of farts comes from gas and mercaptans (other gases) in the mixture.
These compounds contain sulfur.
The more sulfur-rich foods you eat, the more sulfides and mercaptans will be made by the bacteria in you guts, and the more your farts will stink.
Foods like cauliflower, eggs and meat are really bad for making stinky farts.
Beans on the other hand, may make you fart a lot but they aren't usually the smelly kind.
