For me it’s driving while under the influence. If you couldn’t tell, I like me some ganja. However I have long since held the belief that it is utterly insane to drive while under the influence of most substances, with maybe nicotine and caffeine being the exception. All too often I see other stoners smoking and driving, which I simply can’t fathom. I’ve only operated a vehicle once under the influence and it was just to move a U-Haul around the block to a different parking spot, which was such a scary experience while high that I refuse to even consider getting behind the wheel again while high.
Chaos moves are so much fun.
When a friend and I play Coup (hidden role card game), we’ll typically start out playing normally - especially if there are new players - but as things progress, we get into “advanced” strategies. We might not look at our cards at all, and publicly proclaim it, such that nobody can possibly know if we’re BSing or not - since we don’t know ourselves.
My old group loved to do a few blind rounds of coup after we were ready to move onto another game. Made for chaos and great fun for everyone. That was usually our warm up game - still waiting for people to show up, maybe snacks were still being prepared, Hosts walking the dog, etc.
But of course, first round, EVERYONE is a Duke.
