Kyon is the deadpan narrator and central character of The Melancholy of Haruhi Suzumiya, a Japanese light novel series adapted into a popular anime in 2006. Denwa is the Japanese word for telephone, so the clip is simply a character telling Kyon that his phone needs attention. Short anime voice lines like this have become popular online because they are easy to recognise, easy to drop into edits, and carry a lot of character in only a second or two. Fans continue to reuse it as a notification-style joke and a shorthand reference to the series.
