We have a genuine BoM artifact, right in our house!
My formerly TBM DH was having a senior moment the other day, and couldn't think of the right word for the multi-level, carpet-covered things you can buy in pet stores, for cats to play, climb, and sleep on. (Neither can I. . .)
He referred to ours as "the cats' Rameumptom." So it was dubbed, and so it has remained.
