Discover the story of the song > Experiment On Me – Halsey

The protagonist is telling someone that they underestimate her and don't appreciate how well she treats them. They say that they are pretty like a car crash and ugly like a lullaby, and they challenge the person to experiment on them. The protagonist also talks about being seen as too good-looking to be lonely and feeling hopeless but still romantic. They mention the idea of locking up sons and making way for daughters, and say that they don't need a man with so many women around. They repeat the idea of being a car crash and a lullaby, and again challenge the person to experiment on them. The song ends with the repeated phrase "experiment on me."
