If this was a recent occurrence, it may have been from the 6.6.5 kernel. There was a WiFi regression in that version that did exactly that, slowed the system to an absolute crawl. I got hit by it on my PC and ended up hosing my whole install (because I panicked and botched things up), but my laptop was fine. I finally got things reinstalled a couple days later when 6.6.6 was released, which fixed the regression anyway.
My dad’s go to is “Joe’s Bar and Grill, this is Grill speaking”. Sometimes he’ll shake it up and answer as Bar instead
