Tarpin comes from Marseille and southern French slang, where it is used as an intensifier similar to very or really, and the full phrase is a common everyday way to complain about extreme heat. As a short voice clip it spread through French soundboards, group chats and short videos, especially during summer heatwaves when the line works as an instant caption. Its appeal is less about a single known source and more about the recognisable accent and wording, which French speakers reuse each year when temperatures rise.
