It is an abbreviation for “Preachers Kids”
The stereotype behind it is that preachers raise their kids in a very strict household and when the kids get a little bit of freedom they tend to do the most with it.
Thank you for saying this. Not enough Pastors say or do this. I'm a PK. I always felt and still feel like saving the world is more to them. Then I feel guilty cuz they are saving souls but doesn't my soul count too? https://t.co/Lh0rnYvfIh
