Discordians don't really need hexes, because if we want to give someone an interesting time, we simply pray to Eris for them. But praying to Eris is dangerous, even (maybe especially!) when praying for someone else, so maybe a Discordian hex would be a good idea. Anyway, an example of a Discordian hex:
Step 1. Turn to the intended victim. Step 2. Say to them, "You'll be fine! What's the worst that could happen?"
