I remember my husband observing that when our older daughter went to her first high school dance, he learned the definition for "semi-formal" had changed... the girls dressed up and the guys didn't, making it SEMI-formal. It is nice to see the guys who go to the trouble to put on a button-down and khakis from time to time, but they certainly can also look like roadkill. Oh, and I don't think it's hazing... more like, "Hey, Dude, what if we...?" "Yeah, Dude, that sounds awesome!" And I do believe it is fueled by a bit more than Red Bull.
