D1 Shitter
A person who poops with such frequency it's like they're doing a full-time job just to poop.
My cousin’s a D1 Shitter. He poops in the middle of the night. Like it’s his shift.
My mom’s a D1 Shitter. She poops in the car. In the kitchen. Even in the bathroom of the bathroom.
My friend says, 'I'm not a D1 Shitter yet, but I just pooped in my pants.'
