I think your "general usage" is actually fairly specific to particular places and people. Without the explanations, I wouldn't have gleaned the meanings you're assigning (I'm a native English speaker from NZ). It seems pointlessly obfuscated and offensive to me.

Thought I'd go find out if I was being particularly insensitive or if people were clutching their pearls a bit tightly. Couldn't find many examples, but here they are in the wild and not causing any noticable problems.

Firstly, twatproof, from reply #14 in the Festool owner's group to a question about dovetails:

>"I just had a go with the Festool jig and it's the most twatproof solution I've ever seen."

and secondly, cuntproof, on twitter, with someone called Wiryjack describing the term to the award winning writer and naturalist Helen Macdonald:

>"A mechanic I used to know described things as 'cuntproof', which I took to mean foolproof but extra robust to deter the malicious as well as the stupid."

I may note that Helen Macdonald apparently considers cuntproof to be an excellent term, well worth adding to her vocabulary.

This seems like a very strange idea to triple down on. Take or leave the feedback, but I'm not sure you are helped by trying to debate the relative merit of these terms.

FWIW, as a native English speaker I also found your post both needlessly offensive and equally inscrutable.

Fair, I know I am digging a bit of a hole. Partly I am interested in the semantics and partly it is the first time that I have encountered people being particularly pissed off by the concept. Most people I have described it to in the past seemed to find it either funny or useful, so I was surprised by the pushback. I mean, you can say fuck on here and nobody gives a damn, hell, you can name an entire language brainfuck and everybody claps, but this use of language is way out and I am interested in why. I figured that if I dug a little deeper on an already flagged thread, it would not cause any particular harm. Anyone discussing this with me from then on in, is doing so after delving into something clearly marked with 'here be dragons'.
