The phrase comes from a 2010 press conference in Uganda where pastor Martin Ssempa described homosexual acts in graphic terms while campaigning for anti-gay legislation. A recording spread online, was remixed on YouTube, and the eat da poo poo line was isolated as a repeatable meme. Its fame grew through remixes, quotations, and South Park references, turning a serious political speech into internet slang for extreme disgust that still circulates today widely.
