In Kingsize, Jenny Hval reflects on her experience living in New York and feeling disconnected from any sense of subculture or a visionary future. She sings about her fascination with big bananas, which represent something larger than herself and her desires for a bigger, more significant existence. She also mentions her book, Soft Dick Rock, which explores the concept of using traditionally male elements in music to create a softer sound, and refers to her own performance with the bananas as a form of this experimentation. Hval also touches on her Norwegian heritage and the importance of baking, before returning to the central image of the rotting bananas as a symbol of decay and the sense that something is attacking itself. The song overall deals with themes of isolation, disconnection, and the difficulty of finding meaning and purpose in the modern world.
