I wish I had more stories for some of the nicknames I've come up with. I've tried to make the nickname fit the person, just the right amount of snark or contempt or whatever to give the reader an idea of what that person was like--I'm too lazy to flesh things out all the time and I like the mental picture that pops up with the proper nickname.
I came up with some really good ones--like Sergeant Allstate, the insurance salesman by day, sergeant for 1 weekend a month, the cheap and kind of slimy salesman--or Farmboy-san for one of the blackbelts back in my karate days; he really did have a farm, and the whole country-boy thing, but without being your Larry the Cable Guy redneck. But those are pretty much one-story guys. I didn't spend a lot of time around either of them. It's a shame--those nicknames took a while to work out (Farmboy-san only occurred to me this morning!).
Then there are Pocahontas/Piglet (first ex), Number Two (second ex), Scumbag (haven't written much about him, aside from the "Saving Whitney" post a few years ago), Hank (the insane stepbrother) and the Old Man (stepfather), some of whom are regular topics.
Lots of snark. It seems at first glance that I don't have a lot of happy stories. But I intend them to be at least partly funny, rather than just a collection of angry rants.
