Not the Long Duck Dong variety, but names that somehow seem to be incongruous with the person…
When I was taking my Spanish course last year, I stayed with a family in Valladolid. The grandmother was a grumpy, frowsy old harridan who regularly screamed at everyone, and got in my face a number of times about very minor things that the rest of the family didn’t seem to have any problem with. She had quite a presence despite her habit of wearing a faded blue housedress at all times. Quite a piece of work. (THe rest of the family was lovely.)
Anyway, she introduced herself just as la abuela, and I didn’t find out her real name until I took a group photo of the family, and found out her name was … Tinita.
Yes, double diminutive cutesy teenage-girl name. Somehow, didn’t quite seem to go.
