Olin-Sang-Ruby Union Institute, a Jewish Summer Camp in Oconomowoc, WI

It's a place you go to meet friends, hook up, be friends with your counselors, sleep in tents (unless you're a stupif tifi), and learn hebrew, kinda. It's the best place you will ever go, and the worst place to leave. You will go home and feel weird sleeping in a room by yourself, and find yourself singing camp songs alone.
Rachel: Hey, are you going to OSRUI this summer?

Ben: Duh, what the fuck would I be doing otherwise?
