The phrase comes from Russian speaking anime communities online, where fans compile rankings of the most shocking traitor arcs and plot twists. Clips built around that idea spread as a meme across short video edits and soundboards, because almost any disappointment can be framed as a betrayal. It stays popular with anime viewers who recognise the overdramatic framing instantly, and with creators who need a quick label for a backstab moment without explaining the whole scene or pausing the video for extra context at all.
