"​Party Favor (Mahogany Sessions)" by Billie Eilish explores themes of unrequited love and the frustration that comes with being pursued by someone who only wants what they cannot have. The song conveys a sense of detachment and defiance, as the narrator refuses to be complacent or fulfill the role of a disposable "party favor" in the other person's life.

In the verses, the narrator addresses the person they are speaking to, expressing the need to have a serious conversation. However, they also acknowledge that the chances of reaching the person are slim due to the possibility of their number being blocked. This could imply a lack of interest or effort in maintaining a genuine connection.

The chorus embodies the narrator's frustration. They reject the other person's advances, rejecting their pleas to "stay" and dismissing them as empty words. The mention of calling the cops or the person's father reflects the narrator's determination to distance themselves from the unwanted attention.

Despite acknowledging that the relationship could have been handled better, the narrator argues that the circumstances were out of their control, paralleling the inability to change the weather. The mention of misheard songs suggests that the other person doesn't truly understand or listen to what the narrator is expressing, removing any hope for a genuine emotional connection.

Overall, "Party Favor (Mahogany Sessions)" portrays a strong sense of self-worth and refusal to be emotionally manipulated. The song acts as a reminder that the narrator is not an object to be used at someone else's convenience or as a "party favor."
