Not the Black Shorts but Anjem Choudary and the Black Tunics. As always, Wodehouse is our trusty guide:
The trouble with you, Spode, is that just because you have succeeded in inducing a handful of half-wits to disfigure the London scene by going about in black shorts, you think you're someone. You hear them shouting "Heil, Spode!" and you imagine it is the Voice of the People. That is where you make your bloomer. What the Voice of the People is saying is: "Look at that frightful ass Spode swanking about in footer bags! Did you ever in your puff see such a perfect perisher?"
UPDATE: Mr Eugenides has wise words too.
