The 'Everybody Gangsta Until' meme is a popular internet phrase and reaction template used to describe a situation where someone's bravado or tough exterior instantly vanishes due to an unexpected threat. While the phrase has roots in AAVE and hip-hop culture, it became a viral sensation through various images—most notably a low-resolution picture of a character looking tough paired with surreal or terrifying scenarios like a cockroach flying or a teacher entering the room. It effectively captures the universal human experience of losing one’s cool when faced with a minor yet terrifying inconvenience or a sudden shift in power dynamics.
