Not really a pepper per se, just an "emergency preparedness" kind of guy. When does one consider themselves a "prepper"

My wife just sort of humors me and gives me a bemused smile lol. I call everything "emergency" followed by the thing. Example: "ok honey don't be mad, but I just got an emergency camping stove" or "emergency solar light".

That being said, when does one cross from just being a middle aged dad to "prepper" lol? Like what's the dividing line? I have a camping stove, a solar panel and battery by Goal Zero, some solar lights, some emergency blankets (the ones that look like tin foil)...that kind of stuff. I do not consider myself a pepper. I'm more planning for a power outage (which we get around here)

EDIT: Follow-up question does the Butane fuel for a Coleman Camping stove ever "go bad" or expire? I've had 3 cans of it for about 5 years now unused. Are those still good indefinitely? Also, is it safe to use indoors? I'm talking about any carbon monoxide or anything like that.
