Chal bsdk is a piece of Hindi internet slang that circulates as a short, shareable audio meme rather than a line tied to one famous film or show. The phrase is a rude, colloquial way of telling someone to go away, and its popularity online comes from how easily it fits arguments, pranks and roast videos. Creators in India and the Hindi-speaking diaspora reuse it in reels, shorts and WhatsApp forwards, often as a punchline rather than an insult. Its staying power comes from that flexibility: it works whenever a scene needs a quick, unmistakably desi brush-off.
