“Do you” certainly sallies forth from black vernacular, even if the nature of its mundane parts makes its origin Google-proof. The phrase is affection conferred by another person: a “+1,” wrapped inside a fav, tucked inside a like. “Game recognizes game” reflects love of oneself, a kiss upon a mirror. It fixes the observed in his or her place while flattering the speaker: “I’m calling you out for possessing a particular set of skills” (in lovemaking, basketball or macramé), for I, too, am blessed with those very same skills. It takes one to know one.
