I’m afraid I don’t actually know what Antonomasia means 😳
.Thanks for trying guys, you are getting close, but probably not quite close enough.
I’ll try to explain better. In the bike world (or on here at least) someones says I need a full-suss for a bit of all-day riding, someone says Orange 5, thread closed. Just something which is the obvious choice if you see what I mean, there must be a name for those items (if not the marketing people should invent one)
Probably didn’t explain it well first time.

Just googled Antonomasia, not quite that either.
