Actually, this is a term originally associated with Reddit and the chans. When confronted by an obvious beta-male (like the guy in the Post or Times the other day who wrote about letting his wife sleep with other men so that he didn’t try to “own” her sexuality), the redditors (and other “s**tlords”; their term of endearment for like-minded non-politically correct folks) refer to those whipped males derisively as “cucks.” So this term, I believe, is referring to the GOPe huevos-lacking beta-males who we also deride as having no spine.
As the boys at the chans would say, “Top kek!”
Reddit? I have heard of it, once. "Chans"?? No idea. "Top kek!" Clueless.
But I certainly know what a cuckold is, and it's an apt description of a lot of GOP politicians. As you so nicely put it "GOPe huevos-lacking beta-males who we also deride as having no spine." .
I think some of the people scanning this post may have missed that the term was not created by the 'tards, but by the dissident right.
Donald Trump might not be a conservative, but he's clearly also not a cuckservative. Lindsey Graham, Chris Christie, Mike Huckabee, George Pataki? If the shoe fits...
