Scottish slang for a headbutt — delivering a swift, forceful blow with the forehead instead of the fist. The Gorbals, a historically tough inner-city neighbourhood of Glasgow, lends the phrase its streetwise credibility. Like 'Glasgow kiss', its near-synonym, the term packages brutal violence inside the incongruous politeness of a 'kiss', generating a dark humour that feels very much at home in Scottish working-class vernacular. It's well understood across the UK even among those who've never set foot in Glasgow.
