FAPOS is a term for a "Fat Ass Piece Of Shit". FAPOS are a everyday common occurrence. The quickest way to spot a FAPOS is with a quick ocular patdown of the individual's midsection, if it is paunchy, then you have spotted a FAPOS.
"Hey look at that FAPOS over there devouring cheeseburgers."
"Pat has been laying on the couch eating junk food all day, what a FAPOS."
"Anthony, sluggish off gargantuous proportion of goat meat, could barely make it home before succumbing to a deep slumber ."
