Butt hurt sort of implies a violation of an agressive nature. I get over stuff too quickly for it to be called that.
INFJ can mull over stuff for years. Small stuff...ENFJ's too.
You ever had a phone call where some one is talking about a conversation you had with them three years ago, and then they tell you they were really hurt by what you said? Only you can't remember the conversation (but you kinda laugh, because it sounds like some thing you'd say...which sort doesn't help), and you are a little WTF? Why do you guys do that? Why not say some thing closer to the time, instead of ambushing?
This what I call butt hurt, 'cos getting it out at the time is more healthy.
