Not certain where "anyroad" originates, except that it is definitely a Northern expression - Yorks and Lancs, rather than Scouse or Geordie, I think.
But I've heard it in all parts of the land and in every conceivable accent over the past few years. In my youth, it was the stereotypical sort of speech from a "stage northerner."

I found myself using another odd dialect phrase the other day to describe a neighbours son who has a very high opinion of his own abilities which is, unfortunately, not borne out by his actual performance. When my wife retailed the latest assininity of this young man, I retorted, "Oh, well, what do you expect - he's all mouth and trousers."

Now, I have not the slightest idea of its provenance, but this was a common expression in the part of London where I grew up. I've never heard it used outside the Metropolis. Is anyone else familiar with it?
