An oft used insult at my Glasgow-based secondary school would involve the insulter making a reference relating to the odour of the nether regions of the insultee’s mother, whilst suggesting that there had been a degree of physical intimacy between the insulter and the insultee’s mother. The insulter would simultaneously invite the insultee to enjoy the fruits of the said intimacy. Viz: A: Oi you ya wank. Your team’s shite at fitba’. B: Aye, smell yer maw (holding out index finger under A’s nose). The expected response would be A, in turn holding out his own index finger in front of B’s nose, and retorting: - A: Aye, smell yer ain. The famous Scottish humour at work.
