my cousin is from Yeovil and they use "mate" a fair bit there. ...... could have come from there too ....
I like butt too. occasionally comes out . I remember speaking to a quite a young person (I the early naughties) from the heads of the valleys in a bar in Cardiff and he seemed to be from another world again ..... he was very pleasant and used my "butty" to talk about his friend .....which I think is another level again .
