ESFP stands for Extraverted Sensing Feeling Percieving
Did you read up the profile? This is what my girlfriend scored by the way.
I'll try and put it simply, since you don't know much.
The results are given by four letter codes each letter representing a dichotomy (two way) that affects a certain attribute of our personality.
Extraverstion and Introversion which deal with our social energies.
Sensing and iNtuition which deal with how we percieve things.
Thinking and Feeling which deal with how we make our decisions. (Judge things)
J and Percievingwhich have to do with our way of wanting things finalized or remaining open ended.
People who score E get energized by social interaction while people with I get drained with social interaction, and of course there are varying degrees.
Extroverts are typically outgoing and sociable, while introverts are usually reserved and shy. But that's not always how it works, and introvert can be great with people and everyone will love them, but still need alone time to "recharge" if you will.
People who score S are detail oriented and do things in a systematic step by step way and usually are concerned with concrete matters while people who score N are usually big picture oriented and tend to skip steps. These methods usually have their pros and cons, and I'm not too knowledgable on how this one works in real life. But each tend to notice things the other does not. An S will recognize a certain detail wrong an N may have not noticed, but an N can make connections and see things that aren't there. (I think everyone uses both to a certain degree, like when we try to predict "Who did it?" in those crime shows we used to watch all the time.)
Thinking and Feeling are how we make decisions, Thinking people are objective about their decisions and Feeling are subjective. These have their pros and cons too. Most men score thinking and most women score Feeling, but feeling doesn't necessarly mean over emotional.
J types like to make decisions and stick to them, while P types like to weigh their options for awhile and then make a decision, if they still have to. This one is hard for me too. I'll have to do some more research here.
ESFP is called "The entertainer", the life of the party or something like that.
