The phrase is built from everyday Hindi, with 'tu kon' meaning who are you, followed by 'bkl', a widely understood abbreviation for a vulgar Hindi insult used in informal online slang. Clips in this style circulate mainly as short WhatsApp audios and meme soundboard reactions rather than as a named movie or show quote. Its appeal online is the contrast between a simple question and the unexpected abuse attached to it, which lets users turn introductions, arguments, and random messages into a quick comic confrontation.
