What I find disappointing is that some of my hobbies have very distinct real names that go along with them and pinball doesn't. We need one for pinball! Look at these examples below - they don't have "coin" or anything in their name at all. These are real words you can look up in the dictionary. Travel Token collecting has a name and pinball doesnt?!?
Here are some of my fancy named hobbies.
Collecting U.S. Travel Tokens ("Vecturist")
Collect classic Arcade Tokens (falls under "Exonumatist")
Collect some other coins as well ("Numistmatist")
I built a modular audio/video analog synthesizer (in Eurorack, it's name is "TILT" lol) On their forum we are "Wigglers" (wiggling wires, I guess - their forum is called "Muff Wiggler". Explain that web history to your wife)
And some other hobbies without the fancy names: Photography, movies (and foreign movie posters), freshwater aquarium, everything video, synths, and a couple I would rather not share on a public forum.
