The phrase khana tebe is Russian slang for you are done for, paired here with the name Vova, a common short form of Vladimir. The clip circulates on Russian speaking soundboards and chat groups as a ready made threat that needs no setup. Its popularity comes from that contrast between a very personal name and a very generic situation, so editors reuse it for any character about to be punished, caught out or eliminated, even when nobody in the video is actually called Vova at all in real life.
