"Putin khuylo"
The phrase "Putin khuylo" ("Путин хуйло") means "Putin is a dickhead." This language has become very popular as a form of protest against Russian President Vladimir Putin's war against Ukraine and his autocratic rule of Russia. It is especially common as a form of graffiti, a protest chant, or a common refrain in both Russia and Ukraine. Wikipedia (linked below) reports that this phrase was started in Ukraine after Putin's illegal annexation of Crimea and his destabilization of the Donbas.
