SDIYBT

SDIYBT is an acronym for the wild and over-the-top Internet slang phrase that blew up on TikTok and X (formerly Twitter) in 2023. The saying was first popularized by Black Twitter users, who often use humor and exaggeration to clapback at trolls or people being annoying online. Instead of engaging seriously, someone might reply with "SDIYBT” as a way to shut down the conversation while also making others laugh at the sheer absurdity of the insult.

Younger Internet users who thrive on chaotic humor, particularly in meme-heavy communities, are the most likely to use the acronym. For example, they may use it in comments, subtweets, and TikTok duets where someone is doing too much or making a ridiculous argument.

Origin of SDIYBT

The SDIYBT acronym originated in July 2025 from the phrase “Start digging in your butt, twin" The phrase comes from a viral TikTok edit posted on July 4, 2025, by @oe._ytv1, which dubbed a SpongeBob SquarePants scene with the absurd line, sparking a wave of memes, lip-syncs, and edits across TikTok, X, and Instagram.

Internet users quickly shortened the catchphrase to SDIYBT, using it as a playful, over-the-top way to shut someone down online. The phrase's roots trace back to earlier “digging in yo butt” memes, starting with a 2019 NBA YoungBoy image macro and resurfacing in variations through 2024, before the SpongeBob clip cemented it as a mainstream meme.
