Patrick actually used to be popular before Sam bought him some good music.

The line reads like a teasing, in-group joke about how taste—especially musical taste—can reshape someone’s social identity. It suggests that “popularity” is not a fixed trait but something mediated by cultural signals: what you listen to, who introduces you to it, and how that aligns you with a scene or peer group. The humor depends on the implication that Sam’s influence (and her “good music”) changed Patrick’s perceived coolness, perhaps moving him away from mainstream approval toward a more niche or self-defined identity. Underneath the joke is a familiar adolescent dynamic: friendships and romances often function as gateways to new aesthetics that can alter status and self-conception.
