The phrase comes from the Baha Men song Who Let The Dogs Out, released in 2000, which became a global party hit and a lasting sports and celebration anthem. Its barking chorus was soon clipped, remixed and shared online, where it turned into a shorthand joke for chaos, surprise entrances and unleashed energy. The Russian transliteration Ulaki Donsa reflects how the chant is heard and repeated by meme audiences, keeping the original hook instantly recognisable even in short clips. That simple, catchy call and response is why it still appears in edits today.
