Why does the saying, “Making out” refer to kissing and groping? Who came up with and decided to use this terminology to describe this particular act? And why isn’t it “Making in”? Why does everything need it’s own cute name? Why can’t we just call it what it is? Neither word actually describes the act in any way. Along the same lines but even more ambiguous is the saying, “Hook up”. In this case the words partially describe acts being done but doesn’t clarify what those acts are. Did these people kiss? Perform oral sex? Have intercourse? More questions arise when you say, “Hook up” than if you hadn’t used it in the first place.
