The inestimably acute and prolific blog-commenter Subotai Bahadur coined that acronym and has propagated it across the conservative-libertarian corner of the blogosphere ever since. It has achieved the status of an entry on Acronym Finder, for whatever that is worth.

“If ye love wealth better than liberty, the tranquility of servitude better than the animating contest of freedom, go home from us in peace. We ask not your counsels or arms. Crouch down and lick the hands which feed you. May your chains set lightly upon you, and may posterity forget that ye were our countrymen.”
