Edinburgh's own Shirley Manson, international rock legend, rose to prominence with Garbage (via Goodbye Mr Mackenzie and Angelfish, the former of whom were once supported by my own band Little Big Dig at the capital's Hoochie Coochie Club circa 1984.) Here she gives a demonstration of the nuanced swearing that so frequently appears within the typical Scottish person's vocabulary.
Much as I agree with Shirley's points, one key aspect of the subject is that context is everything and swearies are just as commonly used as a positive. Being referred to as a 'guid cunt' in Edinburgh generates considerably greater kudos than simply a 'guid lad/lass.'
Shirley's assertion that the ultimate put down is "fuck right off" is certainly valid; however I would argue the C word will always be infinitely more offensive when wielded venomously. For proof, look no further than this scene from the brilliant English film director Shane Meadows 'Dead Man's Shoes' (2004). In a small Midlands town, a gang of smalltime drug dealers have been responsible for the remorseless abuse of a mentally impaired teenager, Anthony (Toby Kebbell.) His older brother Richard (Paddy Considine) returns from serving in the Parachute Regiment and begins enacting a terrible revenge. Gang member Herbie (Stuart Wolfenden), openly dealing in a social club, comes across Richard. Somehow "fuck right off" just wouldn't have cut it. Richard channels every ounce of malice in his being into three syllables to warn Herbie of the brutal vigilante violence he is about to unleash. The film's excoriating storyline is augmented by strong performances from Considine and Gary Stretch as gang leader Sonny.
