Late-Nights are a popular post-party parties at many college campuses and universities. Similar to pregames, late-nights occur an hour or two after the main party has ended, typically around 4:30 in the morning. Late-nights are characterized by a revitalization of the alcohol supply by bringing out booze that was being saved in closets specifically for late-nights, beer pong (beirut), and dancing. Late-nights are where it's at, and if you remember the 'crazy' time you had, you weren't there.
"Man I have this terrible hangover."
"So the party was pretty crazy?"
"Well the party was decent, but the late-nights where INSANE!!"

quite possible the best invention for college students, EVER. Boston College dining halls remain open until 12 AM on weeknights and 2 AM on Friday and Saturday nights, in order to provide the drunk and/or high students with a wide variety of the most amazing fried food including, but not limited to: chicken fingers, mozzarella sticks, french fries, barbeque wings..

Late Night with Conan O'Brien. The best late night talk show, hosted by Conan O'Brien. Funnier than Jay Leno, much funnier than Letterman, and much much much funnier than Last Call with Carson Daly which is just a stupid show. The band is The Max Weinberg 7, which is better than Leno's Kevin Eubanks because Max actually plays real music and Kevin's too high all the time. But Kevin's funny though and you have to be high to laugh at Jay Leno's jokes as much as he does. The show starts at 12:37 AM.
Late Night is the best show on after 11:30 PM.
