Derived from the Ukrainian football (soccer) chant "Putin khuilo!" (literal: "Putin (is a) dickhead!"), later adopted by the Orange Revolution, "Putin's khuilo" is
Donald Trump, whose appointment of pro-Putin staff, elimination of solidarity-with-Ukraine from the Republican platform (even as that country is being invaded), and
association with Russian mob figures leave little to the
imagination regarding his behind-the-scenes patronage.
The phrase asserts Trump is Putin's condom, or codpiece, as the Russian tyrant fucks the world through influencing the US to accomplish its objectives for it, and intercept the political fallout.
