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).
