&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.
