Can someone explain what "Prim Torture" is?

I've heard this mentioned, but no actual explanation.

I'm assuming (guessing) it's when someone does some nasty things to a prim to achieve something.

I've seen some 1 and 2 prim trees, which normally shouuld be more.
But when you highlight them rather than being a few prim outline lines, there are lines crossing back and fourth all over the place, as if the prim had been twisted and distored in all directions to make multiple faces from 1 item

Would this be an example of prim torture, or is this something totally different?

what you are describing is more than likely a sculpted object, tortured prims are different ...

There is a set of tortured prims for sale on slx for 0L to give a good example
