A word often used by narcissistic scenesters when they describe their oh-so-unique selves in their Livejournal user info pages in attempts to sound like interesting people.
It is a word best used by one person to describe another. Those who apply "quirky" to themselves thereby call into question their very own "quirkiness" by seeming gleefully self-aware (just like everyone else).
