Someone that wants to be a socialite. Someone that has to pretend to be somebody else to get accepted by a group of people, usually because their life would be boring, unoriginal, unimaginative, and plain without the pretense of being this other
intriguing person that people are actually
interested in/pay
attention to, or want to know/want around.
The actress was a natural tomboy and was
naturally loose in social situations, and the dork was so
impressed by her that she was
everything the dork wanted to be (except a scam artist/poseur). The actress wasn't someone people wanted to go away whenever she was around, even as herself, and that was the difference between the actress as herself and the dork when she tried to be herself.
