When you fart and poop at the same time; same as sharting, but PG rated and more relevant due to "parting" your cheeks with more than just gas.
I tried to relieve bloating pressure by farting and parted instead, so I ran red-faced and clenching my butt cheeks all the way to the bathroom while my blind date raced for the exit.

When you get drunk then puke and fart at the same time.
I was huging the toilet and parted over and over.
