Explain SMBC — the wiki for Saturday Morning Breakfast Cereal

This comic shows a couple in bed after sex. The woman compliments the man, saying "I love the way you yell out during sex." He responds awkwardly with "Oh, I... uh... thanks." The caption below reads: "She'll never know about my high school sweetheart, Ogodohyes."

The joke plays on the common trope of someone accidentally calling out another person's name during sex. In this case, the man appears to be exclaiming "Oh god, oh yes!" during sex, which his partner takes as enthusiastic exclamations of pleasure. But the caption reveals he is actually calling out the name of his high school sweetheart, who is conveniently named "Ogodohyes." The humor comes from the absurd coincidence of a name that sounds exactly like an exclamation of sexual pleasure, allowing him to inadvertently get away with what would otherwise be a relationship-ending faux pas.
