"you go girl" origin
I know this is fairly recent and American but I think it must have emerged while I was in the UK. Is it connected with a televison show? Any ideas?
Thanks

It goes back to at least 1985. I found a site that mentions a Tennessee walking horse by that name (as the dam of another horse).
