The commonplace greeting, "What's up?" is evolving in two directions at once. The monosyllabic mob have shortened it to simply " 'Sup?" an interrogative that sounds remarkably like a dinner invitation to my aged ears. On the other hand, the apostrophe averse favor the edgier "What up?" sans contraction.
Since I'm a uniter, not a divider, I propose the convergence of these two forms, in the interest of preventing further splintering of our language. I suggest we all adopt "Tup?" as the preferred form of this largely rhetorical question.
Similarly, plying the same metonymical trend that leads to calling business people "suits," we could refer to doctors as "scrubs."
So "Tup, scrubs?" might be the hallmark of a new millenium Bugs Bunny.
