A shit-baby occurs when you get backed up for days. Let's just say that sometimes people need some fiber/activia/laxative etc. When you get backed up for days the belly starts to protrude and people my think you are pregnant because of the rounded stomach.
Girl 1: Hey girl are you pregnant?
Girl 2: Nah, I just haven't pooped for 3 weeks.
Girl 1: Oh I see. You have a shit-baby.
Girl 2: Well yes I do.
