1) Gollum-like; Scrupulously follows you or the limelight wherever it shines;
2) Is an irritant;
3) You can’t get out of your house no matter how hard you try;
4) Sometimes wears your clothes out;
5) Naturally offends tastes;
6) Thinks they're a social butterfly.
"Nope. You're boned."
Guy 2: Ohhh, he's just a social moth. Nobody likes moths...
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.
A loner 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.
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!
Guy 2: "I feel you on that one Guy, not if she was the last woman on earth, but what other girl do we know that plays COD and makes us sandwiches?"
