P.K. is a common nickname for today's subjects; "preacher's kids". Its pretty easy to see how they got their abbreviation. See you take the first letter of preacher and the first letter of kid and put them together with a period in between and after. That's how we get the term P.K..
Now that a bit of the history is out of the way let me get down to the nitty gritty. I will forewarn you that I'm aware when religious subjects come up people tend to get defensive. With that said I still decided this was the topic for today and I'm willing to deal with comments. Keep in mind though, as with any of these things I write, I know that there are exceptions to everything.
You may think that with a walking talking Bible at home they would be a little more on the reserved side. In my experience with P.K.'s, its been quite the contrary. They have seemed to be like those catholic schoolgirls; that the moment the bell rings they pull their skirts and socks up and unbutton a few buttons on their shirts. (Not that I blame them, those skirts are uncomfortable, just ask Britney Spears)...
Children of preachers always seem to start their revolt around 13/14 years old, 8Th grade or H.S.. It usually starts with the music, they go from DC Talk and gospel to Bone Thugs, Eminem, and DMX (OK, maybe that was just me). They justify by saying that the song "Crossroads" talks about heaven and God, so the parents allow it. From the music they change their clothes, once they change their style they are accepted into a different group of friends. This new group of friends allows them to be more susceptible to the things of this world; sex, drugs, and rock-n-roll. (Like I said before this is a clear over-generalization, but I have grown up in church while moving around, and witnessed this first hand more than once. Maybe its a rebellion toward their parents, maybe towards organized religion, or maybe they just realized who "they" really are. I don't know where the behavior change stems from, but I do know that it exists.
The ones who make it past the rebellion stage without turning into Ozzy Osbourne wannabes typically go on to follow in the fathers footsteps, starting the cycle over again. Now, I'm not making light of losing faith or rebellion against parents. I'm simply observing and reporting what Ive witnessed, its a blog (this is not TV where everything is true people). When beings are under constant scrutiny to believe things or to act a certain way it appears once given enough freedom they do the opposite just because. Its like if you never let your dog play outside, every time the door opens he is going to try and bolt. Not to compare P.K.'s to humans, but you get the point.
There is one thing to say though, in my experience with them they are almost always the life of the party. This may be because they grew up with no TV in their home. Thus forcing them to devise games where you drink the top shelf sacrament wine papa had hidden, followed by jumping off of furniture. I don't know why they called him papa, it just felt more forbidden that way. Nothing else to say.
Watch out for these crazy sons of P.K.'s (daughters too)
Peace be with you... And Also with you.
