Pretty sure the term "prepper" is just shorthand for "doomsday prepper" or something to that effect. People who think the collapse of civilisation is, if not imminent, a strong possibility within the next human lifetime and are preparing for that.

I am definitely not that. I just take precautions against the specific emergencies that occur where I live with a level of regularity.

Blizzards knock out power for hours sometimes into a day or two once or twice a year. We have multiple earthquakes a day, typically in the M1 to M3 range, but M7+ are once a decade events, M9+ are once are century events. Being ready for reasonable natural disasters isn't prepping, it's just smart
