"Aristocrat" makes many references to France and the Baroque era, with the song's setting being the Palace of Versailles prior to the French Revolution. The song title and chorus both reference the aristocracy, which historically was the highest social class below the monarchs during this time period. A "Marie" is mentioned in the second verse, referring to Marie Antoinette, the last Queen of France before the French Revolution. Poppy also lists three types of Baroque era dances in the song's bridge: the courante, bourrée and allemande.
In a 2018 interview with the Zach Sang Show, Poppy stated that the song is about her "sneaking into a party where a lot of famous people are". She later claimed that this was based on a true story and that it happened before she became famous. When asked how she snuck in, she said that she climbed through a window, despite her saying that she "got here from the gutter" in the song. She did not reveal whose party it was, though she said that it was a "secret party" and the person hosting the party was not aware of her presence.
