The sound comes from French comedian Paul Mirabel and his sketch Je me suis fait racketter, in which the greeting Salam les khoya sets a familiar, brotherly tone. Khoya is widely used in French urban slang, borrowed from Arabic, to address a friend or brother, and the phrase has travelled well beyond the original performance. Shared on soundboards and reused in short-form videos, it now works as a quick cultural shorthand for a warm, joking hello between friends, which keeps it popular for introductions and reaction edits.
