I'm convinced he genuinely enjoys making a scene spraying diarrhea on himself. People sit and watch in horror, occasionally trying to let him know what he's doing, and then when some splashes on them, he says "aha! gotcha!"

Meanwhile he's soaking in his own fecal material. 900 posts of pure spatter. If it sounds absolutely maniacal, that's because it is.

There is no getting through to this person, might as well let them just sit covered in shit.
