o'dark thirty 

Same as o'dark hundred. Way too fucking early to be outside working--or patrolling, if you are in the military.

By the time I got off, it was o'dark thirty.

O&A Army 

A legion of pests, nudges and assorted freaks who listen to Opie and Anthony and attack both the media and radio hosts who try to mess with O&A. Tactics include crashing message boards, jamming phone lines and ordering goodies for the radio station they are attacking.

Phillips Phile, Shannon Burke, and Russ Martin all felt the fury of the O&A Army.

O'Berry 

To be sooo phenominal, that people will drop all their plans just to hang with you.

You are the Star of the Bar, The King of the Karaoke, and the life of the party. people all strive to be like you and be in your inner circle.

To be an outcast is to be in a social coma!

"hey dude, wanna hang out?"

"No, I'm hangin with an O'berry"

"AWW MAN, I'm Jealous!"
