The song describes a situation where the protagonist encounters the "other woman" at a grocery store, realizing that she has been having an affair with her partner.

She watches as the "other woman" checks out with a bottle of Cabernet, a symbolic reference to the indulgence and deceit involved in their relationship. The chorus reveals the protagonist's perspective and how she plans to handle the situation. Although the "other woman" may think she has fooled the protagonist, she is unaware that the protagonist is well aware of the affair.

The protagonist acknowledges the cruel world that awaits her partner outside of the affair, suggesting that he will continue seeking other women, just as she did before. The song implies that both the protagonist and the "other woman" will end up hurt and disappointed. The chorus repeats, emphasizing the protagonist's knowledge of the affair and her plan to let the "other woman" have her partner.
