When you mistake quantum mechanics for your dating life! The meme brilliantly plays on the similarity between describing a romantic partner as "curvy, interesting, and hard to understand" and the actual properties of Schrödinger's wave function in quantum physics.
That sinusoidal wave isn't your girlfriend—it's the mathematical representation of a quantum particle's probability distribution! The punchline hits with the Schrödinger equation at the bottom, which describes how these wave functions evolve over time.
Dating may be complicated, but at least it doesn't require solving differential equations... usually.
