Pergi mampui comes from everyday Malay and Indonesian slang, where pergi means go and mampui is a crude, playful twist on mampus, meaning die. The clip spread as a forwarded Whatsapp audio, the kind of short voice note people save and resend instead of recording their own angry reply. Its popularity comes from that shared use in group chats and meme pages, where a dramatic dismissal says more than a typed argument. It remains a go to reaction for moments of mock frustration online.
