AKA "mud touched the cotton"

When you soil your underpants due to an unexpected shart.
Please note that this is the extreme case of a shart in which the fecal matter explodes beyond the crevice of your butt crack and makes contact with your undergarments.
Harold pushed his fart out so hard that the mud touched the cloth. His wife regrets making the bean burritos.
