A guy in college with connections. The Big Man on Campus (or BMOC) knows
people. He's privy to the locations of the best parties, the coolest hangout spots, and the loosest women. The term isn't used as much anymore due to the advent of internet social networking, allowing everyone to "know
people"; but still, being a BMOC takes skill in real-world networking. BMOC's aren't always douchebags, but
may have a slightly more inflated ego than most.
BMOC: "Ok, guys, I
got us all invited to this sorority party tonight, and I know a liquor
store we can stop at that doesn't card."
Other guy: "Whoa, check out the
Big Man on Campus! Awesome, dude!"
