"rot" means "decayed/decomposed". It's got a negative connotation.
In my head it was just part of solid and rotation which was exactly that the code did and all I ever thought of, but once the other person pointed it out it was like "oh, right".
Yes but what's the "dirty" meaning? What were they pointing out? It's not aparrent.
Seems so. I don't know what it is, but I'd rather not Google for it myself.
