Experienced while sitting in a hot car, a smallish pocket of intestinal gas escaping your anus and rather than being released for all to enjoy, you enjoy it traveling in a civilized manner toward your gooch.
Shut up or I'll release this fart bubble of death.

A bubble that stubbornly resides within the chambers of your anus that requires extra force of the bowels to release usually resulting in a fart amplified five to ten times in loudness.
A fart bubble was stuck in my butt in the middle of English, I really wanted to get it out so I forced and that resulted in the most embarrassing moment in my lifetime.
