"
Keith: Dave, would you equate the terms "a disgrace" and "thick cunt" in normal discourse?"

Perhaps a mystery is solved?
Perhaps this is what is meant by "snooty" in the rules? If you use the insult ""a disgrace" you are being snooty, unkind, argumentative and impolite. If you use the insult "thick cunt" you are being unkind, argumentative and impolite.

That would be something to ponder if I still bothered to ponder such things.
