POS 

Parents Over Shoulder
Often used during a phone call where you want to talk about things which would be inappropriate in front of parents. So then one says POS and the other person on the line knows not to talk about that subject anymore.

phone call between two friends
"so what was his name and how far did you guys go"
"POS"
"ok i'll ask you later, can't wait to hear play-by-play!"
