Brushing the cow’s tail

Have you heard this expression before? You know, used as: ‘don’t go brushing the cow’s tail’ or ‘he was brushing the cow’s tail’?

How about, ‘it was so crazy it was as if she was brushing the cow’s tail’?

I didn’t think so, neither have I. Nor do I want to. Although, small part of me wishes for this expression to start up. I wouldn’t mind being the proprietor of ‘brushing the cow’s tail’. Better to be the proprietor of ‘brushing the cow’s tail’ than ‘walking the way with dinosaurs’. I don’t even know what that means. Actually, I don’t know what either of them means.

Disregard I said anything.
