Explain SMBC — the wiki for Saturday Morning Breakfast Cereal

This single-panel comic shows a man in bed trying to convince his uninterested partner to have sex by invoking quantum mechanics: "Aww come on, baby... according to quantum mechanics, there's some probability we're already having sex." He is misapplying the concept of quantum superposition -- the idea that particles can exist in multiple states simultaneously until observed -- to suggest that in some quantum sense, the act is already happening, so they might as well make it official.

The humor lies in the absurd misuse of quantum physics as a seduction technique. While quantum mechanics does involve probability distributions and superposition of states, these apply to subatomic particles, not to macroscopic human activities. The man is essentially using scientific-sounding language as a pickup line, hoping that the veneer of intellectual authority will be persuasive. This is a recurring SMBC theme: characters who weaponize scientific concepts for personal gain, particularly in romantic or sexual contexts. The woman's unimpressed expression makes it clear this approach is not working, which is the real punchline -- no amount of physics jargon can substitute for genuine consent and interest.
