I'd agree with ENTP's typically being trolls but disagree that they usually know when to stop or how to turn on the charm to get back in a person's good graces. I don't appreciate being trolled and not interested in people who do it. Once I realize a person likes to do this, I don't see myself being friends with them.My ENTP brother-in-law is one of the best trolls I've ever seen. He is amazing at knowing what pushes people's buttons, and at knowing when to stop. Of course, sometimes he gets it wrong, but then he turns on the charm until he's back in the person's good graces.
I'm an INFJ and do enjoy practical jokes. That's about the closest to trolling that I get.
