I'm relaxed, it's a funny discussion.
But anyway, that's magnetic pole reversal, which is a thing that happens, yes. The original topic (as the title shows) is geographic pole reversal. Which is not a thing that happens, except when planet-sized objects hit each other. It's not impossible, though; see Venus and Uranus. But yeah, that's... unlikely, to say the least, and the least of our worries if it does happen.
