An extremely niche one I've complained about before is members of the rationalist community using rationalist lingo in contexts in which it is obviously inappropriate, as part of some kind of weird cargo-cult approach to in-group membership. I once saw a guy saying that he had an "irrational prior" on believing X over Y.

If it's irrational, it's not a prior. Stop it.

Why? You can have beliefs and they can be irrational. If the situation calls for symmetry, but your prior is asymmetric because “something tells you it can’t be otherwise” then irrational could be a good descriptor.

In your link, you had other, more seemingly valid, complaints which people addressed well. This one feels like BEC.

If all you're doing is going by your gut, you shouldn't pretend otherwise. An "irrational prior" is indistinguishable from a "gut feeling", but it's draped in the language of dispassionate, disinterested analysis.
