I returned to my shooting videos, at last. A man was explaining a lot about how to shoot at a moving target and then said something like: we used this phrase 'eyes and thighs' to illustrate the process of working of the eyes and the body together.
At first I thought it was just an odd phrase but something in his tone suggested that it was an idiom of some sorts. I then wanted to check and fed it to google. I use this trick quite often to see how much hits do I get. I didn't use quotes at first and re-checked with quotes. It appears that though neither of you has ever heard this phrase it was in fact being used often enough. I also added the word 'idiom' and didn't succeed. Well, it appears it is just a coincidence.
@chaika, but what's an idiom? A couple of rhyming words that describe something abstract enough, isn't it?
