- "The Law of Unintended Consequences."
- The thing about this phrase is that people often cite it, but never define it. There's a good reason for that: any definition of it would be shorter than its title! Let's try: "Unintended Consequences happen." Wait, I think we can do better: "Shit happens." Yup, there it is: when you want to say "shit happens", or when you want to make the Nelson "ha-ha" laugh, you can instead invoke The Law Of and suddenly you sound erudite.
"Triumphalism."
- I'm pretty sure this used to be called "gloating." But by ismifying it, you can pretend it's a school of thought.
Stop using these phrases. If you hear someone using them, smack them. Thank you for your cooperation.
