Very tangentially inspired by @NeilYoung’s “names for parents” discussion: what wonderfully random yet logical nicknames do you/your friends/family etc have? More convoluted the better. My examples:
My high school friend Colin was called “Malcolm”. Sounds random, but no: his surname was Campbell, and at the time Campbell’s Meatballs were advertised by the character “Malcolm Meatballhead”, so Malcolm it was.
Similarly, to my home village’s boomer generation, I’m known as “Young Roger”. This is because my dad goes by his middle name Miller, and after Italia '90, his chums/cronies/acquaintances/colleagues/sympathisers/compadres/associates/contemporaries/well-wishers started calling him “Roger” in tribute to the ageing but prolific Cameroonian striker Roger Milla. I have the same name as my dad and also use the same middle name, hence the “Young Roger”.
What you got?
