Increasingly used label for a core group of liberals who call talk shows and write letters to the editor pretending to be Republicans. A method of trolling popular among left-wing Democrats who believe conservative Republicans are all gun-totin, Bible-thumpin, inbred monobrows who won't detect the fact they are being trolled.

Crypto-liberals will claim they used to be Republicans, back when 'all Republicans were moderates', i.e., before the Tea Party "took over".
