On Turkish social media, sa and as are everyday shorthand for the greeting selamun aleykum and its reply aleykum selam, exchanged constantly in chats, comments and gaming lobbies. Adding baba, a familiar word for a friend or older brother figure, turns the polite exchange into a relaxed, humorous greeting between people who know each other well. Short clips like this one circulate on soundboards and in meme edits because they are instantly understood by Turkish speakers, even without context, and they work as a quick, friendly acknowledgement in videos, streams and group chats.
