Liberal arts 360

When students of a liberal arts college do a 360 degree scan to make sure that someone they know doesn't sneak up on them and eavesdrop on a conversation (read: gossip) about them, since apparently liberal arts colleges are tiny and you're always at risk of someone you don't like running into you

Kayleigh: Did you hear what Ashley did at the frat party last night!

Megan: Girl hold up! We go to Oberlin where there's less than 3000 people on campus and everyone knows each other! Do the liberal arts 360 first to make sure no one listens in!
