In the dissenting opinion regarding DOMA, Justice Antonin Scalia referred to the arguments in favor of gay marriage as "argle-bargle". Now, I know it doesn't mean exactly the same thing as fiddle-faddle (although it is pretty close), but argle-bargle very much reminds me of fiddle-faddle. And as we all know, Fiddle Faddle is the name of a caramel popcorn snack treat (made by ConAgra Foods). And so that made me think that perhaps someone should create some delicious snack treat called Argle Bargle, and sell it in order to raise money for pro-gay marriage legal battles at the state level. (If it were successful, it would be a nice barb to Scalia and a fun riposte to what I and others thought was a rather jerky dissent.)
BTW: This is a language piece on argle-bargle and Scalia's use of it in the DOMA dissent:
