Used actually in the plural context, sloppy ploppies are a bad case of diarrhea in which should not even be wished upon the worst of people. Sloppy ploppies not only is diarrhea which is brutal to have to begin with but on top of that you feel like a rainstorm of shit is coming down out of your asshole which is actually being called down by imaginary natives rain-dancing around a fire set on the hairs your choda & around the rim of your asshole.

So not only do you get the worlds worst case of ringsting, which makes it hurt so bad to wipe, you get the terrible plops which make you wipe 100 times.
