A turd that has been flattened slightly by the pressure of a toddler's booty on his or her undies or diaper. Essentially, a sheem is a poop that has been executed covertly and then squished. Usually there is some reluctance on the part of the sheemer to acknowledge that he's carrying a load, probably because he's in the midst of potty training and doesn't want to get with the program.
Today (says my three-year-old son about another kid at daycare), Brady had a sheem in his pants and it was in his diaper because he doesn't go on the potty!
