Blowout
Also called blow out, blowouts, diaper blowout, nappy blowout, poonami, poo explosion
A blowout is when a baby's poop escapes the diaper, up the back, out of the legs or even through the front. Parents also call it a poonami, a blend of poo and tsunami.
How it's said
...intent on increasing my washing bill to astronomical amounts. If it isn't daily blowouts, it's at least several times a week!
Any recommendations for the best size 4 nappies to contain blowouts would be very appreciated!
I never once had a blow out as they are fully elasticated at the waist and legs.
Who says it
Where it came from
Blowout is the noun from the verb blow out. Its older senses include a tire that bursts and a sudden gush of oil and gas from a well. Wiktionary now lists a diaper that overflows and leaks beside them, with poonami as its synonym.
Diaper brands use the word for any poop that leaks out of the diaper, and some add newborn blowout for the messes of the first weeks. A UK store guide on how to survive a poonami calls it the dreaded nappy blowout.
