Oh there’s a word for this. The first time I was in the U.S. I was looking for an ATM and someone said there was a biyouvet down the road. I wasn’t sure what a biyouvet was but it sounded French and exotic. I asked them if the biyouvet had ATMs and was assured it did, and went on my way to find the aforementioned biyouvet - before I could though I found a Bank of America which did in fact have ATMs.
