The phrase comes from Russian internet slang, where lokh is a long used dismissive term for a gullible loser or sucker, and attaching it to a first name turns it into a personalised meme roast. Clips like this circulate mainly as short soundboard audios and chat replies rather than from a known film, song or show, so the exact original recording is unclear. Its appeal is its specificity, which makes it funnier for groups who know a Viktoria, and it keeps being reused as a ready made punchline for fails and friendly teasing.
