Smart Mark
Back in the days of Kayfabe, there were two types of people you'd encounter at Professional Wrestling events: "marks" and "smarts". Marks were the common rabble in the seats, the folks who paid to see the show they thought was an actual athletic competition. On the other hand, Smarts were people who knew the truth about wrestling, that it was a staged athletic exhibition with no real competitive aspects. Usually, smarts had a connection backstage to wrestling, and most of them worked either for or with a promotion.
As the truth about pro wrestling became more widely known, a third class of people came into being in between these two: the Smart Mark, or "smark" for short. Smart marks knew the whole thing is staged, but enjoy it anyway. They tended to look to different things in a match than marks did; while a mark would like a wrestler mostly based on how his character was portrayed, a smark would like a wrestler more based on his in-ring performance. Nevertheless, smarks did not have any real connections backstage; they simply enjoyed the show.
These days, since the vast majority of the pro wrestling fanbase (at least those over 5) tend to fall into the smark category under the old definition, the definitions have mutated somewhat. Now, marks are the people who follow wrestling casually and tend to care more about the drama and the storylines than the actual construction of the match, and smarks are people who study and analyze matches, root out backstage gossip, and generally take wrestling more seriously (in other words, wrestling geeks). Few marks have enough knowledge of the business to self-identify as marks; indeed, the term is more often thrown about by smarks as an insult. Another perception of the term "Smark" is that it is an incorrect term and shouldn't be used. Connection with the business is required to be a smart, ergo, no one who isn't in the business can be anything other than a mark. Of course, as the internet gets bigger and more wrestlers, especially independent ones, develop an online presence, that definition fudges as well.
It used to be an axiom that smarks and marks did not get along. Nowadays, factoring in the ever growing gray area between the two, it's really not that bad. Many marks are capable of saying "Wrestler A's matches bore me, I take a bathroom break when he's on", and many smarks are capable of saying "so what if Wrestler B isn't technical perfection in the ring, his character entertains me". The advent of the internet has allowed the two communities to mingle as they didn't back in the days of the newsletters and video tape trading, and the line between smark and mark, such as it is, has blurred significantly. The negative perceptions on both sides of the divide come from the extreme edges of both camps - the smarks who nitpick matches half to death looking for trivial flaws so they can rate popular matches "DUD" on the 5 star scale and feel intellectual, and the marks who shrilly accuse anyone who criticizes WWE in general or John Cena or Triple H in particular of being that kind of smark.
Although smark is still exclusively a professional wrestling term, similar groups has emerged in other forms of entertainment. For example, there are people who watch a show and enjoy it, and leave it at that. However, there are other fans of a show who delve into the online community, especially entertainment news and "spoilers" about shows. In this instance, a "mark" would sit and anticipate if a sick character is going to get better, whereas a "smark" would go online, find out that the character's actor is considered horrible to work with, notices his contract is expiring soon, and realizes the character is probably about to be McLeaned.
