“Shelfie” is a brilliant term; not originally mine, of course, I’ve seen it first in the Boardgame Group (sorry, THE BOARDGAME GROUP) and I love it. It’s such an “our” thing – really, only board game hobbyists even understand what’s the pic owner is proud of (while most muggles won’t even understand what they’re even seeing in the picture).
It also made me come up with the other two words. We seem to generally like words.
