I'm not exactly sure who you're arguing with, or what the criteria is for a name to be cute, but I can think of a lot of cases which seem like to me like counter-examples, where a silly name was taken seriously:
- 'Brexit', if I recall correctly, was originally a joking play on 'Grexit', back when the Lib Dems were the only major party supporting a referendum, but went on to be taken very seriously.
- 'YIMBY' is a silly name based on another silly name but has done a fairly good job building a coalition and getting policies enacted even in the face of severe public choice problems.
- Refering to HB 1557 as the 'Don't Say Gay' bill has been quite effective at getting respectable people to oppose it despite the phrase itself being silly.
- #MeToo and #BelieveWomen were quite successful movements for a while despite the silly names.
- 'RINO' has been used as an effective attack line against moderate republicans.
- 'Junk Bonds' were (probably?) so named by the guy who popularized them.
- 'Unicorn' status is a prestigious thing for a startup to aspire to.
Also, I don't understand your 'woke' example, though you say it "basically speaks for itself." I think activists have been hugely successful with the name, using it to highlight a threat and gather an international coalition of politicians, academics and voters to push back against it. A few years ago woke stuff seemed irresistible, but using the label has now taken us to a place where some people can earnestly suggest that 'woke is dying' - though I think that is an overstatement. The fact that the name is a bit silly hasn't prevented it from being a potent rhetorical device for movement building.
Flagging that GPT-4 is making things up here. The book didn't come out until much later, maybe 2015, the term predates the book, and I'm not sure whether Yudkowsky coined it.
The earliest usage I've found is this 2008-11-19 Robin Hanson post in what was retroactively designated the "AI FOOM Debate".
