Despite being among the "Rawls joke getting set," I think a more-easily-grasped phrase for the phenomenon Orin Kerr describes is "rubber glue-ism." At least among Americans, the insult "I'm rubber and you're glue, and whatever you say bounces off me and sticks to you" has more currency than a formal understanding of Rawls's theory of justice.

I didn't quite understand what Kerr was looking for when his post first appeared, but if John Holbo's assessment of it is correct, then the idea that an opponent's tactics can be both decried and imitated seems to be well encompassed by a childish retort.
