E.g., Rain, Feather, Apple, Cocoa, Bird, Tree, etc.
Name some of your own if you'd like!
Didn’t Michael Jackson name one of his children Blanket?
What I recount below is a small glimpse of this phenomena, it does not attempt to analyze it fully.
In my own family, this silliness has gone on for generations, and in my late teens or early twenties, I finally figured out at least a piece of the puzzle. Not restricted merely to my family, it’s also cultural.
There are some of my relatives with given names such as Peaches, Candy, Spike, etc. They were all born to teenaged mothers, most of whom were too immature and extremely unprepared to care for and raise babies. The names they dumped on the children represented something they liked, be it a toy, a food, a cartoon character, a color, and so on. The three examples I show above used to be repeated in various forms throughout the Black community in the US years ago. I am not in contact with a lot of people who are parents or expectant parents of babies, so I do not know if it’s still happening.
:(
I wasn’t aware that Blanket is his nickname, thank you for the clarification.
