I was what you call a barbarian back in college: that's what they call the guys who didn't belong to any fraternity or organization.
I attended a lot of org orientations however though admittedly it was mostly for the free sandwiches. Free food is free food after all.
After a while the organizations holding the orientations caught on and just gave me the food, sparing me from the hassle of pretending to listen to the speaker talking about the orgs.
Ah, those were the days!
