Is there a similar expression to "pearl clutching" without the gender implications

I generally like the expression "clutching their pearls" as an expression of exaggerated shock or scandal. However, its origins in women's jewelry gives it a sexist bent that I'd rather avoid. Is there a similar phrase with the same general implications, but without the gendered lens?

Solution 1:

Economist and NY Times columnist Paul Krugman often uses "shocked, shocked" to characterize elites who overstate their disapproval... his usage contains more than a hint of a sneer at disingenuous hypocrisy, but it has the benefit of avoiding a gendered connotation.

"I see that the Washington Post editorial board is shocked, shocked to discover that the incoming Republicans aren’t serious about deficit reduction. Who could have suspected?"
