The line comes from the official Russian-language version of Portal 2, Valve’s 2011 puzzle game. GLaDOS, the artificial intelligence antagonist, delivers it after being awakened and recognizing the returning test subject. The original scene is remembered for turning a simple greeting into a hostile, sarcastic reunion. Localized versions let players recognize the same character moment through different performances, and short excerpts are often used in gaming edits when someone familiar returns unexpectedly. Its brevity also makes it effective as a compact reaction clip.
