Standing at the roadside, waiting to cross a busy road in Cardiff - a stranger comes up to me and says "Oi Butt !!! There's a zebra crossing down by there" to which I replied "Well I hope he's having better luck than I am"
According to a BBC show I saw recently about policing in The Valleys, Butt basically means mate. I just about choked laughing hearing one of cops call a guy he was nicking 'Butt til they explained it
