When you have a particularly bad case of the beer shits, and you keep thinking you have to crap, but all that comes out is a turd the size of a cork and a gallon of air. You go through the day not being able to trust your anus, feeling like you need to fart, but fearing you might chuck the plug.
"How's your hangover?" "Not good. My headache is gone, but I keep dealing with a series of fart plugs.". "Lovely". "Yeah, the fifth one I shot out was under so much pressure I nearly cracked the toilet."
