Fluorescent Adolescent" is a song by the English indie rock band Arctic Monkeys, released as the second single from their second album Favourite Worst Nightmare. It was released on 4 July 2007 in Japan and 9 July 2007 in the United Kingdom. The song was written by Alex Turner and Johanna Bennett, Turner's girlfriend at the time, in a hotel room prior to the recording of Favourite Worst Nightmare. The song is a ballad about getting older and finding out that life isn't as fun anymore. It describes a woman who dreams of her youth while her current life is unsatisfying and boring, with emphasis on her sex life- this is reflected in the opening line, "You used to get it in your fishnets, now you only get it in your nightdress, discarded all the naughty nights for niceness, landed in a very common crisis". "Fluorescent Adolescent" is one of the band's most popular songs, and is frequently performed as a closer to their concerts.
