P-O 

A person who's attitude and agression will P-O some people shortly after meeting him. A P-O is usually a large domineering man, but has the mental age of a 15 yr old, full of pointless aggression bottle in an oversized adults body

Per came into the room, red in the face screaming at a worker about something gonme wrong, other turn toeach other and say what is PO babbling about now?

PROBATION OFFICER. Just about the coolest job anyone could ever have. They give you a cool badge that got me out of a speeding ticket on more than one occasion. Juvenile Probation is the best, you get to yell at punk ass kids all day long. So what if they threaten to kill us, it's all in good fun! We ride around the city all day and witness junkies sitting on their front steps smoking crack and wangsters smoking weed. People duck away from us when we ride by, like we care if they kill themselves slowly. We don't have to carry a gun, and if the kids run away from us we don't have to chase them. Best of all, everyone thinks you are a law-abiding citizen b/c you are a P.O. What a bunch of dumb-asses.

Officer: "Do you know why I pulled you over?"
P.O. "I am a Probation Officer"..
Officer: "have a good day.."
