The phrase itself is a traditional Islamic greeting in Turkish, with Selamun Aleykum meaning peace be upon you and Aleykümesselam as its customary reply. On TikTok, creators turned the everyday exchange into a short audio trend, using the back-and-forth rhythm as a greeting, a punchline or a way to introduce a character. The clip spread through duets, skits and greeting videos, where its familiar sound and playful timing made it instantly recognisable. It remains popular because the greeting is both culturally familiar and easy to drop into almost any opening.
