The best nicknames are the ones that people don't know they have.
Isn't that just making fun of someone behind their back?
I realized that connotation, too. See below.
Found out after working at my job for two years my nickname among the guys is Mamacita, lol.
But really, I openly call people by their nicknames, mostly just to see their reactions. All in good fun, nothing derogatory.

I learned associations years ago. Usually with a mental picture and a word.
