Back in the twentieth century, American girls had used baseball terminology. “First base” referred to embracing and kissing; “second base” referred to groping and fondling and deep, or “French,” kissing, commonly known as “heavy petting”; “third base” referred to fellatio, usually known in polite conversation by the ambiguous term “oral sex”; and “home plate” meant conception-mode intercourse, known familiarly as “going all the way.” In the year 2000, in the era of hooking up, “first base” meant deep kissing (which was now known as “tonsil hockey”), and the groping, and the fondling; “second base” meant oral sex; “third base” meant going all the way; and “home plate” meant . . . learning each other’s names. Getting to home plate was relatively rare, however.
