Well, some dead-ons from RJ. I'd be the Prepster, of course, exactly what it is, from a social function as it's captioned (from the original pic, not the iPhone composite, shown only in my private pics).
Most of the guys here have the Work Out Shot, naturally. But many of the others also represented, even the Girlfriend. And what IS that V-gesture with 2 fingers sidewise? Got a few of those here, too. Thanks, amusing piece.
