Streaking was popular when I was in college - never partook myself.
It was about -30 when the entire population of the next dorm over decided to streak. Unfortunately it was also midnight and the doors of all the dorms except the main entrance were all locked. They eventually made it back to their dorm and the worst thing was hardly anybody saw the show.
I ran with a couple who loved to do over-the-edge stuff (past college age); she'd streak a party, and the hubby would outdo her by doing what he called a "Stroll"...he'd get buck nekkid and just kind of mingle for a couple of minutes.
