Tung Tung Tung Sahur began spreading on TikTok in 2025 as an Indonesian brainrot meme about a wooden log character holding a bat who appears at sahur, the pre-dawn meal during Ramadan. The tung tung sound imitates the kentongan drum traditionally used to wake people to eat, turned here into an endless chant. It joined the wider wave of absurd brainrot characters shared, remixed and dubbed in other languages, including Russian versions like this Sakhurchik edit, and remains popular because the rhythm is instantly recognisable even without context.
