Post Shit Fart(s) or PSF syndrome

after taking an exceptionally large shit, the series of farts that come afterwords to really clear the bowels out.
Johnny:"Damn why do you keep farting?! you just took a huge dump!!"

Joey:"Dude im having a Post Shit Fart(PSF) attack right now, my body is just making sure theres nothing left in there."
