The phrase refers to Seine Saint Denis, the department numbered 93 north east of Paris, which has a strong place in French slang, rap and football culture around local pride and banlieue identity. This particular recording has no confirmed source, singer or original video, and circulates mainly as a very short WhatsApp audio passed between chats. Its life online depends on recognition of the slogan rather than context, so it travels as a ready made reaction that French speaking users can drop into conversations, edits and soundboards without any explanation needed at all.
