Eh blin is a common everyday Russian expression of mild frustration, roughly meaning oh damn, and it has circulated online as a short reaction clip rather than from a single known film or show. Russian speaking creators began dropping it into edits and chats as a deadpan response to small fails, and it spread in the same way a bruh moment spreads in English meme culture. Its appeal is how universal the feeling is, so it keeps being reused as a quick meme reaction for mistakes and bad luck.
