sacrificial diaper

When changing a baby, an unworn diaper that's ruined as a result of an especially messy blowout situation, but prevents the surface underneath from being soiled as well.

Whoa! Looks like this new diaper is going to be a sacrificial diaper, there's poop flowing everywhere!

poo-splosion

When a baby has such a massive poo that it shoots out the top and/or leg holes of the diaper.

Oh no, the baby had a poo-splosion! Now we both need a change of clothes.
