The phrase comes from Chilean Spanish, where 'querai' is a casual spoken form of 'quieras', and the full line translates roughly as 'whatever you want, I will pay for it'. It circulates online as a short voice meme, shared in chats, reaction videos and short-form clips whenever someone makes a bold or expensive request. Its appeal comes from the contrast between the grand promise and the everyday setting, which makes it easy to reuse across different jokes. Because the line is short and instantly understood by Spanish speakers, it continues to spread as a flexible reaction sound.
