That’s not actually the definition of it. It’s what happens when someone is severely constipated for so long that their intestines stretched and can lose muscle control of their bowls resulting in a “leaky” bum or actually have entire bowel movements without being able to stop it or feel it until it’s too late. Quite a few children end up in ER with this, including my granddaughter. It can take months to years of good bowel program to be able to recover full control.
