Although standing for 'Peice Of Shit', pos is an offshoot for a universal adjective to describe someone in a negative way or it can also just be used as a noun that is the equivalent to calling someone a negative name.

Red Teletubbie .The only teletubbie that isn't female or gender confused. unlike tinky-winky, (the other male tubbie), it does not own a purse. he instead owns a scooter, capable of speeds of a whooping 6 miles an hour.
Dude, Po is being such a pompus ass running around with that expensive scooter, and we're stuck with these shit toys.

Short for Pulse Oximeter.
A PO is a device used to monitor the oxygen in a patient's blood. It shines light through a patient's finger, toe, nose, earlobe, or the patient's forhead, and another sensor on the other side of the light wave measures how the light is being absorbed.
