What exactly qualifies as a "stable" overclock?

I've seen some other answers, but just wanted some clarification. When exactly can you say that an overclock is stable?

Have a i7 7700k that I've been messing around with. Been mostly using Prime95 v26.6 to test temps, decided to use it for quick stability tests as well. Just as an example, after a few bumps up and down of voltage/clock speed, got to a point where Prime95 didn't cause a BSOD the second it started up, and the temps were acceptable. Looked good after 10 minutes, so I opened up a browser, fired up a few tabs. Still fine. Next tab though, BSOD. Obliviously unstable, right? But that got me thinking, is it expected that a CPU being utilized at 100% would have issues when trying to throw other things at it? That it should perhaps BSOD? Or should it be able to balance whatever is thrown at it, at which point it's truly stable?

For example, at stock speeds/voltages, should I be able to load up Prime95, a couple of demanding games, and encode some video files, and expect that while there may be some lag/hang-ups, it'll be able to juggle the load/voltage, and there shouldn't be any fatal exceptions, BSODs and the like? That that actually means it's stable, and that I have to up voltage until I can theoretically do something similar when overclocked?

To me, a stable overclock is an overclock where the clock speed is not thermal throttled, runs 20 Standard Trials of IBT w/ AVX as a first test, and 1 hour of Prime95 Blend, then does not lockup or BSOD anytime during video editing, gaming, streaming and daily usage.

For you you should make sure your 7700K keeps below 90°C when overclocking, at higher voltages of 1.3V+, 80°C.
I would consider it stable if all your programs work without problems and BSODs. Those tests are only good for troubleshooting, no use of torturing components just to see when they'll brake up. Leave them run long enough and even best server will throw an error sooner or later.
