A baby mistaken for a monster turd.
Joe: Man, look at that guy. I heard he was a toilet baby.
Bob: Dude, what?
Joe: His mom thought she had to drop a deuce, but it turned out that she gave birth when she found him swimming in the crapper.

A crap so large it resembles a crowning infant. Stitches may be required to reassemble the anal port.
After Thanksgiving I had a toilet baby that was so large, I was in poop labor for 3 hours.

A miscarried baby fetus found in the toilet of an unhappy mother. Can be either retrieved by animal control (225- 774-7700) or flushed depending on ones plumbing.
Bethy and George had a long-distance relationship because Bethy lived in Texas and George lived in Canada but they still managed to keep the relationship going for about 3 years without a problem, but when they ran into their first relationship problem they both agreed that the long-distance thing made it too difficult to resolve the issue and thus decided to end it, resulting in Bethy going out to clubs and whatnot and meeting a new man named Drew who took her to his place and got her pregnant, and they were very happy with this and bought a large quantity of baby products and had a baby shower but unfortunately Bethy had recently taken to drinking and smoking despite her doctor's advice not to and thus had a miscarriage which she discovered when she was on the toilet one night after a long day of clubbing but she was too grossed out by the fetus to take it out of the toilet and so she called Animal Control to remove the toiletbaby.
