I don't know, it was something I'd only heard once or twice before. Given the context, I could only assume it was a trope.
It's okay, Nayt. Colmars have this weird ability to make everything they say sound like a well-remembered quote or reference, even when they're making it up spur of the moment. It's a game I like to play called "Apt or Happenstance?" And it happens about once a conversation.
It does not help the overall feeling that I'm playing rhetorical catch-up every time I try to have a conversation with both of them at once.
