More or less the opposite of both a loner and a of course, a social butterfly, from which the term gets its name.
prefers to do things his or her own way, and because of this avoids social contact and does not wish to be part of most groups.
A social butterfly
is typically the life of the party, they have connection with all cliques and are generally well liked even if only for shallow reasons. They thrive in any situations that would allow them to flex the interpersonal skills.
A social moth
on the other hand desperately wants to be a social butterfly, they look up to and even idealize the social butterflies they know; but secretly wish people would love and respect how "wonderful and unique they are" They try to befriend people who they deem as worthy of their praise and often chase around those that actually do have good social skills pathetically hoping to snag some of their glory.
Tim: I used Facebook
to invite everyone to the party on Friday
Zack: I saw it, and I got an email from Bethany with some decoration suggestions.
Tim: I didn't even invite her. Last time she harassed everyone by trying to hand out dozens of political fliers when they left.
Zack: She heard about the party and invited herself, she's a social moth!
