@eribosot huh, I thought I had goldbrick right, with the "swindle" transitive verb meaning and the story of the gold brick swindle with "the con artist's practice of passing off bricks made of base metal as gold" (Merriam Webster). But I guess you don't allow two correct answers and swindle is probably too broad vs the specific definition you gave for B.
@v_for_verbosity You know what, I'm giving you a point for that. I completely made up that definition without reading the usage note, but it fits.
@eribosot you probably ought to give it to Rupert, the Void and Tiggy as well then 🙂
