@cstross I’m partial to a nice spot of barratry, myself.

My former barrister brother-in-law said that barristers on opposing sides of a case (who were often friends outside the courtroom) would sometimes challenge each other to include specific obscure words in their speeches. After having successfully introduced, say, "walrus” into a speech, the barrister would then, with great solemnity, cause a note to be passed to opposing counsel that just said "Neener neener neener”.
