Similar in nature to a Social Butterfly in that they are attracted to social events, or anywhere a number of people are gathered.
The main difference being that while a Social Butterfly is usually more outgoing and well liked by their social group(s), Social Moths gather around the popular people & places without being particularly popular themselves, much like a moth is attracted to a bright light.
Social Moths usually aren't particularly attractive or talented and tend to lack any real personality so they gather around people with those qualities to make themselves appear more interesting.
Not to be confused with a Wallflower who may actually have a great personality but is generally just introverted or shy in large groups.

Tony: Yeah, he's a total Social Moth, showing up uninvited and hangin around all the popular people but he really doesn't have many friends.
