The exact source of this doston clip is unclear from the available information, but the word itself is widely understood across Hindi and Urdu speakers as a way of addressing friends. That familiarity helps the sound travel easily in short-form edits, reposted audio clips and messaging app forwards. It stays useful because creators can drop it at the start of almost any group-based joke, especially in regional meme content where a quick spoken setup feels more personal than a text caption.
