This is where the title takes a dark turn. "Infidelity" in this universe isn't a passionate hotel room tryst. It is "abject"—it is wretched, it is low, it is a systems failure.

Only the initiated know that buying “abject infidelity” today means you are purchasing a bottle of actual, high-quality lubricant that has been re-labeled as fake to avoid import taxes—a double bluff.
Is there a specific where you first encountered this title?
