The phrase comes from the id3 title SAMPLER'S PARA DJ'S, suggesting a Portuguese-language DJ sampler pack where short announcer stingers were sold for use in live sets and radio spots. Sampler vocals like this have circulated since the CD and early MP3 era, passed between DJs as ready-made intros for weddings, clubs and local events. Uploaded to soundboards, this version found a second life as an ironic intro meme, used whenever someone wants an ordinary moment to feel like a grand DJ entrance.
