If they're spending all this time hooking up, when are they finding the time to study? I'm skeptical. I think media people (and some freepers) are having difficulty distinguishing between Girls Gone Wild videos and reality.
We did not refer to it as hooking up in the old days (college student in the late 70's), but a rose by any other name ... And I went to college in the pretty conservative midwest.
Studying gets done during the day (ok, afternoon and early evening), and the extracurricular activity between the genders during the night.
