When you attempt to fart, but not enough effort is exerted
so the gas bubble creeps or is suctioned
back inside. You end up having to wait until
it re-forms before being able to expel it.
A: DAMMIT, I got a bad case of backdraft!
A: I tried to fart but it crept back inside because I didn't force it hard
enough. Now I'm all bloated and constipated-like.
