Bad Blood

The lyrics describe a friendship damaged by conflict. The speakers remember being young and feeling they could rely on each other, but over time resentment has grown. They seem tired of revisiting the dispute and ask for it to end. The mood shifts from warm memories to frustration and a wish to move on, even if the friends now go separate ways.

“Bad blood” is an idiom for hostility or ill feeling between people; it is not literal blood. Asking for it to “dry” suggests letting the conflict fade, while “let it lie” means leaving the matter alone rather than reopening it. The repeated idea that small moments “define” the friends suggests that ordinary shared experiences can become lasting parts of a relationship.

The song holds two feelings at once: the past still matters, but looking back too much can be painful. The memories are described as binding the friends together, even as resentment pulls them apart. It is unclear whether the speaker hopes for reconciliation or simply wants the argument to stop. The repeated refusal to talk may express exhaustion, avoidance, or both.
