The line comes from The Goonies, the 1985 adventure film directed by Richard Donner, where it is shouted by Sloth, the gentle giant played by John Matuszak, as he meets the group of kids.

It spread through TV references, reaction GIFs and YouTube compilations before becoming a staple greeting meme for streamers and editors, who use it to announce arrivals because almost everyone recognizes it instantly.
