The 'Dude, you have no Quran!' meme stems from a viral video capturing a heated street confrontation between a young man and a Christian street preacher. The phrase became an instant internet classic due to the shouter’s high-pitched, desperate delivery and the sheer absurdity of the argument. Initially popular in niche religious debate circles, the clip eventually transcended into mainstream meme culture, often appearing in 'shitposts' or 'brainrot' compilations. It is typically used to point out when someone is speaking authoritatively on a subject they clearly lack the primary sources or credentials for, or simply to mock high-stress social interactions.
