War on Fun
The War on Fun is an orchestrated campaign by the administration to prevent students from going to any parties except for the co-opted, regulated, lame "events" sanctioned by aforementioned administration.
A prime example is the way the university converted the popular "40s on 40" into a much less exciting "40 Days" event.
The ongoing NYPD crackdown on loose restrictions on IDs in local bars if often lumped in with the "war on fun," but is merely an unfortunate coincidence.
Students looking for fun should probably start getting to know downtown and Brooklyn. You came to Columbia so you could party in the city rather than a frat anyway, right?
