What is O Line?
When your largest (er...widest) friends hang out together. Most often used when the group of wide friends walks down the street and deters foot traffic, like linebackers.
Also useful because you get to make the "O" face like Office Space. Oh. Ohhhh.
Friend #1: Ravi called up the fellas to the all-you-can-eat buffet. They're going clubbing afterwards.
Friend #2: Man, that's one hell of an O Line.
