Get too emotional about their relationships, analyze them for months after breakup, try to advertise how personable, socially adept, or emotionally sensitive they are to people around them, come up with zany schemes, try to teach others about the emotional side of life, play the role of the "psychologist" or moralizer or "people analyst". Like with ENFps trying to depict themselves as Se doms, it comes out as forced and inauthentically gaudy, and the details you learn about their lives don't correspond to what they are trying to show of themselves. I used to know this ESTp who would stress his superb social skills and personal sensitivity, but then I witnessed him be a rude jerk to a random guy who was trying to help him. At that point it became evident that he's only putting on a show when he was trying to convince me and his other friends of how interpersonally sensitive he is, and that it wasn't true.
