Bannon calls Kushner a "cuck" — and what that even means

A brief history on the term cuck: The term "cuck" is short for a much older term used often by Shakespeare — "cuckold," which literally refers to a man whose spouse is unfaithful.

Origins: The word was derived from the cuckoo bird, whose females lay their eggs in different nests.

Racial insinuation: In pornography, the cuckold was most often a white man whose white wife cheated on him with a black man, according to GQ.

Political use: During the 2016 election season, the term became a favorite of the alt-right to describe mainstream Republicans who did not support Donald Trump — "cuckservatives" — whom they saw as weak.
