👉 A 'warming bernabel' is like a thermometer that's so cheerfully overzealous about its readings that it gives a high temperature when the weather isn't hot, but somehow still sounds like it's quoting a Shakespearean sonnet about the joys of a sunny day. It's a fancy way of saying a thermometer that's more concerned with sounding sophisticated than actually being accurate.
Here's an edgy example sentence: "The warming bernabel predicted a 'perfect' day of rainbows and unicorns, while the thermometer was just banging its head against the wall, convinced it was hotter than a disco ball on a summer night."
