Abbreviation of "Pussy Pound Out." Used when discussing sex in a context--particularly sex that just happened--in a situation where discussing sex is not appropriate. Especially useful when at work. It is actually an extremely polite way to crudely discuss one's sexual behavior, and is increasingly considered the best form of etiquette when discussing sex among certain circles.
On the phone at work:

"Grady! Did you get those PPOs taken care of yesterday?"

or

"Yeah. Not just one PPO last night, but three! Things are going great!"
