One I heard recently on a panel that I've never heard elsewhere, but richly deserves to be a buzzword:
The outrage industrial complex.
In reference to Democrats hyperventilating over the latest thing Trump recently said, and their tea-leaf reading the usual racist connotations into whatever Trump's ambiguous remark. Related to Trump securing the border, getting Mexican cooperation, and wanting to deport about a million who crossed illegally, were permitted to stay here, didn't show up for their court date, and were after review denied the legitimate basis to stay here.
It's been a good week for Trump. That generally gets the Dems torqued up to a whole new level of crazy and race-baiting.
