I'm a bit like KoalaBear and see people by their nicknames - just can't help it. Therefore Enid is 75 with grey hair and a tweed skirt, MascaraO'Hara is Irish with too much eye make up, Cod a big fish, SuzyWong is a Malaysian ladyboy etc etc
For me, it is not worth delving any deeper because I'd definitely get it wrong!!
