The phrase comes from everyday Turkish, where selam is a common greeting and bu arada means by the way, so the clip works even for listeners who catch only the friendly tone. It circulated as a short reaction sound on user generated soundboards, shared in its brief wink tagged form. Its appeal is timing rather than context, a one second hello that can be dropped into gaming clips, chat compilations, and edits whenever someone joins late, returns after a pause, or wants to steer attention elsewhere without a long introduction.
