Refers to a rip-roaring
case of "liquid farts" --- not just a case of mundane "trots", but a full-
blown bout of "galloping
diarrhea", like you're actually urinating out of your large intestine.
My country-cousin friends graciously invited me to help myself to the leftovers in their fridge while I was visiting them for a couple weeks this past July. That was all great, except that once I made the
mistake of thirstily polishing off a nearly-full 2-quart bottle of Ocean Spray Premium Prune
Juice over the course of a couple hours on an especially hot
day. Well, needless to say, I was then obliged to stay in the yard for the next couple days 'cuz I had to run inside and visit the Little Boys' Room every ten minutes, plus I hadda remember to not eat anything after four in the afternoon both days, so that I could eventually "poop myself empty" by late evening and thus be able to get some sleep at night! Talk about total colon-
pee --- my poor
butt-hole got so sore that it felt like I was squirtin' out hot lava towards the end of it! Ah, well --- live and learn --- prune
juice isn't meant to be consumed in large quantities (I shoulda gotten a clue from the fact that the bottle had had so little used out of it), unlike
apple or cranberry
juice that comes in the same kind of bottle!
