The phrase comes from the Turkish track Alayına Bam Bam by Müpto Baba and Miçe Baba, where selam bebek ben kelebek appears as a memorable sung line. Clipped from the song, the short excerpt spread through Turkish social media, edits and soundboards because the wording is easy to quote even for non speakers. Its mix of greeting, confidence and absurd imagery helped it become a reusable reaction sound, and it is still shared when someone wants a playful, self assured introduction in a video or group chat.
