<human>: In this case, when I say 'stress fart', I'm talking about an action or movement that puts pressure on your abdomen and/or blowhole muscles and you are forced to release gas (I think the most often one is from sneezing). I call this a "stress fart". I'll start:

This morning, I was in a particularly long line at the bank (why the fuck are so many people at the bank so early in the middle of the week?!). After about 10 or 15 minutes, I was roughly half way through the line. The lifesaver mint I was enjoying had gotten small enough for me to start chewing it... BIG MISTAKE. Somehow, I accidentally sucked a tiny piece of 'life saving' mint down my wind pipe, and I started to cough. Naturally, nothing is worse than coughing and choking like a dumbass in a public place - so I tried my best to stifle the sound and not die from a piece of candy. After a few coughs, I started to feel like this thing was never coming up, but then suddenly one last forceful heave brought that sharp little bastard up. I was relieved that the piece was no longer threatening my oxygen supply, but my tiny celebration came crashing down when I realized a dozen or so pairs of eyes looking at me. I immediately realized I had let out a fart during the last cough. Now, if you know them, stress farts are NOT regular farts. They are accidental, and due to the muscles being forced to release them sound as if they are under extreme pressure (read 'loud as hell'). I know everyone heard it because it was so damn quiet in there you could have heard a mouse fart - and that was NO mouse fart.

Can you condense the text into a few key points?
<bot>: I saved myself from choking to death on a piece of candy by heaving and coughing, but released a massive fart in the middle of a silent and crowded bank.
