The phrase comes from Monte, the online name of German streamer MontanaBlack, whose casual, Hamburg-influenced slang became part of his on-stream persona. Kuss, meaning kiss, paired with Diggah, a familiar term for a friend, turned a simple greeting into a recognisable sign-off for his community. As short clips from his streams were shared on social platforms and soundboards, the greeting travelled beyond his regular viewers and became a handy shorthand for playful affection in German meme edits. It remains popular because it is instantly recognisable, easy to drop into a video, and warm without being serious.
