An especially long and loud anal eruption of putrid gas, brought on by sudden physical stress, such as bending to lift a heavy object.
My mom was bending over to lift a large sofa, when she suddenly blew a stress fart. I could not believe it, I'd never heard my mom fart before!!

an especially foul-smelling, raunchy gaseous explosion created by the churning of one's own stomach due to unhealthy levels of stress.
"Damn. That smells awful. Do you need to change your pants?"
"No it's all good. Just a stress fart created by the upcoming block exam."
