I graduated from the local university over three years ago, but I still live in the same apartment just east of main campus. While the building I am in is filled with university students, they are primarily grad students, so it is relatively quiet, even on the weekends. Someone may occasionally have a party, but even then it is typically done by 11PM, and the guests headed home.
When I was a student, I would occasionally attend parties on campus. The ones hosted by the fraternities and the sororities were certainly the best. It was not necessarily the alcohol which made them "the best," or the theme parties (pirate night, beach night, casino night, and plenty of other nights) which made them "the best," or even the people who attended the various parties which made them "the best."
What made them "the best" for me was the plethora of "extracurricular studies of human anatomy," as a friend of mine would call them. On a typical Friday or Saturday night, even during the summer, one could walk down Sorority Row or Fraternity Row and hear plenty of sounds of college students engaging in various sexual activities. Even if the music pouring forth from a particular fraternity or sorority house was loud, one could still usually hear a loud primal cry wedged between the pounding thumps of the overamplified bass lines. The later into the Friday or Saturday night, the more of these loud primal cries one would hear, and those cries – at least at the fraternity houses – would very often be followed almost instantly by a chorus of (usually male) cheers.
The other five nights of the week, it was possible that one could walk down Fraternity Row or Sorority Row and hear such similar cries piercing the night, but with significantly less frequency. On Sunday nights in particular, it was extremely rare to hear such sweet sounds. Whether the sky was full of stars or full of rain clouds, whether the temperature was summer hot or winter cold, many students would walk up and down Sorority Row and Fraternity Row at night, especially on a Friday night or a Saturday night, listening to the sexual sounds spilling past the windows and onto the sidewalks.
