A mongoose is (A FART) the presence of a mixture of gases known as flatus in the digestive tract of mammals expelled from the rectum (SHOT OUT YOUR ASS, OR SOME ELSE'S ASS). It is more commonly known as 'farting', 'passing gas', or 'breaking wind'. Flatus (THE FART) is expelled under pressure through the anus (THE ASSHOLE), whereby, as a result of the voluntary (PUSHING IT OUT) or involuntary (WHOOPS, SLIPPED OUT) tensing of the anal sphincter, the rapid evacuation of gases from the lower intestine occurs. Depending upon the relative state of the sphincter (relaxed/tense) and the positions of the buttocks, this often results in an audible crackling or trumpeting sound (LOUD OR LOUDER), but gas can also be passed quietly (SBD, SILENT BUT DEADLY)). The olfactory components (STINK) of flatulence include skatole, indole, and sulfurous compounds (NASTY ASS SMELLS). The non-odorous gases are mainly nitrogen (ingested), carbon dioxide (produced by aerobic microbes or ingested), and hydrogen (produced by some microbes), as well as lesser amounts of oxygen (ingested) and methane (produced by anaerobic microbes). Odors result from trace amounts of other components (often containing sulfur compounds)(ROTTEN EGG SMELL).
