Posting countless photos of ones own face and body on myspace and facebook in swimsuits, lingerie, and "sexy" attire in various "sexy" poses from "modeling photo shoots," hoping for multiple complimentary comments.
That rather unattractive girl in an ugly swimsuit with far too much makeup on is narcissistic.
A person who is vain and self-centered, and who spends a fortune to preserve his appearance. One of the traits of the yuppie and, of course, the fag, who spends hours admiring himself in the mirror.
