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.

O'Hair line 

looking beyond the the common five-head, this gleaming forehead giganticus is so large it was named after the massive Chicago airport because you could easily land a 747 on that vast skinscape.

Who is she kidding? Bangs can't hide that O'hair line of hers.
