It was released as the sixth single from McKenna's debut studio album, What Do You Think About the Car?

[1][2] The song was written by Declan McKenna and produced by James Ford.

Talking about the song, McKenna said, "I love big powerful choruses that you can just scream, and I wanted this to be one of those.

I remember writing it just sat home alone with my sister’s guitar in complete euphoria with only a chorus written and nothing else, just shouting the words which are super vague but just summed up all the confusion and frustration I’ve had the last two years.
