I learned this expression several years ago, the first time I tried to get one apart & back together. I called the guy who suggested a 1911 to me and he said "It's called an idiot scratch".. I had about the same feeling that you experienced when you saw this little plastic thing..
I have since learned to try not to do it but it doesn't bother me..
It's not much of a marketing angle, is it.. "Buy this because you're an idiot"..
