L Lawliet, known simply as L, is the eccentric detective at the centre of Death Note, the manga and anime series about a notebook that kills anyone whose name is written in it. While L is usually quiet and analytical, moments of raised emotion stand out, and clips of his scream have been lifted by fans for anime edits and reaction videos on YouTube and TikTok. The sound works because it is instantly recognisable to Death Note fans yet funny out of context, so editors keep using it to sell shock, defeat and dramatic irony.
