The stupid that erupts from the DUmp, cannot be measured on the Richter scale!
You know, that's very interesting, sir.
When I think of the primitives, and Skins's island, and the rampant stupidity erupting from therein, the first thing that comes to mind is an exploding septic tank, bubbling and popping and splattering out excrement all over the place.
It's a sight I actually saw as a little lad, in New Jersey. I dunno if "septic tank" is the proper word for what it was, given my rather young age at the time, but that it was a tank that dealt with the processing of used commode water, well, that was rather unmistakable, even to a six-year-old.
It was like a geyser, even.
I have no idea, but there you have it.
And so every time the primitives are especially stupid, that's the first image that pops into this mind.
