An explosive shit babies make in their diaper. It is on a grand scale, blowing out the sides and tracing down the extremities, leaving parents absolutely mortified.

Essentially a diaper explosion.. The phenomenon that occurs when a baby has such an explosive shit, the results spurt out of the diaper and trace down the extremities. Clothing is ruined and the baby needs an entirely new wardrobe change-out, with the stained clothing simply being thrown out.
