At one school, and I actually forget which, “sustainability” was definitely the buzzword. The tour guide said “LEED-certified” a gazillion times throughout the tour, assuming everyone was familiar with the term (I only had a vague idea myself, to be honest), until finally, near the end of the tour, one parent bluntly asked, “What is that thing you keep saying, ‘Lee certified’? What is that?” Tour guide looked a little flustered, LOL.
A cappella was big, too.
