Hundreds of students ditched their clothes to run around the school's campus in just their underwear.
The tradition of the "undie run” began 11 years ago on the last day of regular classes as a way for students to blow off steam before studying for finals. The first year, just a handful of nearly naked coeds took part.
But it's grown over the years, with the party getting wilder and wilder. However, after complaints of public intoxication and a number of students saying they had been groped, the school had had enough.
This year, school officials put a ban into effect, with the dean of students issuing a statement: “Due to significant concerns about safety for CSU students, the university will not allow the 'undie run' to take place this year.”
At first, it looked like the ban was holding. But then, hundreds of students, all wearing their undies, came running through campus, chanting "you can't stop us" repeatedly.
Campus security tried to bring the situation under control, but it didn’t work.
