Explain SMBC — the wiki for Saturday Morning Breakfast Cereal

This comic depicts a bar scene where a man tries a cheesy pickup line on a woman: "Hey baby, looks like you could use some sexual healing." The woman responds matter-of-factly, "I don't think that'll cure my recto-vaginal fistula" -- naming a real and decidedly unromantic medical condition. The man's face drops in horrified silence.

The final panel reveals the woman cheerfully telling her friend, "Wow! Med school is already paying off!" The joke is that she has learned just enough medical terminology to weaponize it against unwanted advances. By responding to a sleazy come-on with graphic clinical language, she completely deflates the man's attempt at flirtation. The comic celebrates the woman's clever use of her education as a shield against bar creeps, while also poking fun at how quickly medical knowledge can make social interactions very uncomfortable.
