Before joining MN I had never heard this expression. I've seen it explained a few times and am clear on the concept. Now, recently something has happened to make me think a guy is a potential cocklodger. I don't think, if I hadn't read the word and its description that I would have understood this. So AIBU to think that by inventing this word and defining it that a new concept has also been invented which allows us to see something that previously would not have been that simple?
