A guy who finds himself pretending to be someone he is not, to obtain closeness with a desired member of the female species.

Before P & R, I could remember my nights, tagged photo's on facebook were not interesting and a good time usually meant wine, cheese and Disney's Scene it. But that is no longer the case.
