Duan liu qin is a Cantonese idiom, pronounced dyun luk chan, meaning to cut ties with all six categories of kin, and it gets used online as a hyperbolic way to announce someone has been disowned. The phrase circulates as a short voice note in WhatsApp meme culture, where voice audios are forwarded between group chats and turned into punchlines for family arguments, gaming betrayals, and mock feuds. Like other Whatsapp forwarded audios, its humor comes from the over-serious delivery clashing with trivial drama, which keeps it in steady rotation for creators making disowning jokes.
