PPJ
Acronym for "Price Per Jump". It is the amount of money you had to expend in your effort to get laid. If you spent $150 on dinner and a show and got laid twice, your PPJ would be $75. The PPJ includes all expenses that resulted in your having sex, not including any costs you would have incurred anyway during your normal daily activities. So if you normally would have driven 2 miles, but you drive 3 miles in order to get laid, your gas money for the last 1 mile counts toward your PPJ. The act of having sex resets your PPJ counter back to zero. If in the course of getting laid you avoid spending money you otherwise would have spent, your PPJ for that jump can actually turn out to be negative number.
Man, my PPJ for last night with Sharon was $300. I might as well have hired a hooker.

Dude you've been with her for 2 months and you haven't had sex yet. Your PPJ must be astronomical by now!

She paid for dinner and drinks! I ended up with a negative PPJ! :)

PPJ
Pill Popping Jukebox is a term used to describe DJ's who only play other peoples songs. They will tend to dance around playing with controls on the deck in front of them as if they are contributing somehow to the music.

PPJ's often feel empowered by the fact that people are dancing to the music being played while they are behind the deck.
When infact most people in clubs will dance to anything that is played, often dancing to sound checks.
