a west of Scotland colloquialism for a cheap, fortified wine, usually Buckfast Tonic Wine. For some unknown reason, drinkers of "singin' ginger" want to befriend total strangers, not by attempting to have a conversation with them, but by singing incoherently. "Ginger" is another colloquialism used by the indigenous peoples of Glasgow. This refers to soft (carbonated) drinks, such as Barr's Irn Bru, and fortified wines are perceived as "grown-up's ginger". Hence, over-enthusiastic indulgence of alcohol causes the GINGER to make one want to sing.
See that wee alky bam?.. He's single-fished oan the singin' ginger!
