The line comes from Harry Potter and the Chamber of Secrets, when Harry first travels by floo powder from the Weasley home and tries to name Diagon Alley. His unclear delivery sends him to Knockturn Alley instead, turning a simple journey into an accidental detour. Clipped to just over a second, the mangled word has circulated online as a compact joke for mistaken destinations, because listeners do not need the full scene to understand it. Its brevity, clear Harry Potter connection and instantly recognisable slip keep it useful for edits about getting lost.

A short voice clip of Harry Potter saying diagonally instead of Diagon Alley in the floo powder scene, often used for wrong turns and travel mix-ups.
This very short clip captures Harry Potter attempting to travel by floo powder and mangling the name of his destination, turning Diagon Alley into the single, confidently misspoken word diagonally. His voice is young, hurried and slightly muffled, as if he is speaking through smoke and coughing, which makes the mistake land instantly even without any picture. Listeners recognise the slip at once, because the familiar place name collapses into an ordinary direction word, and the effect is a small, warm laugh rather than a dramatic moment. It works best as a quick punchline, a sudden wrong turn in an edit, or a gentle joke about getting lost.
