Poopstain can be used as an insult or a thing. The definition of Poopstain as an insult is a stanky girl or boy that cant keep his or her hygiene in check, but not the mild smell like the horrible strong sent you cant even smell Axe over the sent its really bad. She/He has all the mouth in the world and then is quiet when some one steps to them. The definition of Poopstains is the action is having a shit stain in your boxers or panties this is embarrassing and unnecessary
