Well... Have you ever wondered this question. Many people I have talked to always say things along the lines of, " Well, I'm a true diehard Cubs fan and always will be."
Ok, Lets look at things logically. What is a regular fan compared to a diehard fan. Well, if you want to look at it from the side where a regular fan is just someone who cheers for the home team in the city they are from, then that I guess is a reasonable answer. You could also argue along the lines of well, that is who my parents root for, and that is who my friends root for, so I guess I will root for them too. These are both appropriate answers in my mind. Now, what is a diehard fan? Someone who follows the team no matter what the conditions, win or lose, they will always be there to cheer them on. This is what I consider myself. These two types of fans are examples of basic levels of fans.
Lets see, you could classify many types of fans. But how many? Here is what I have come up with personally. (Notification) I am looking at this through the many different types of Chicago Cubs fans.
1. Regular Cub Fan - Somone who cheers for the Cubs if they just happen to be on TV. They want to see them win but if they happen to lose... Well, tomorrow is still just another day. They have no main reason for rooting them on other than thats who they like and there is no rhyme or reason behind their logic of choosing them. Thats perfectly acceptable in my book.
2. Maternal/Paternal Cubs Fan - Someone who cheers for the teams that his/her parents cheered for. This then keeps the tradition alive and is a perfectly good reason to cheer for a team. Gotta reproduce for some reason right? Why not reproduce to increase a fan base. LOL
3. Underdog Fan - This can be defined in any sport. But mainly for the Cubs, for the reason they have been the underdog for so many years. This is a fan that would rather see the unlikely team win. I know many people who, when watching a sporting event, will ask who the likely winner is and then root for the other team to win. This is again perfectly acceptable... (unless for instance the two teams are the Cubs and the Cardinals and you are in a Cubbie bar and you root for the Cardinals because the Cubs are expected to win. You should then be shuned for life.)
4. The Wrigley Fan - Now I know this is a borderline fan but I have heard instances where people have used this to descride some Cubs fans. A Wrigley Fan, aka a Yuppy, is a Cubs fan that only goes to the game to be a part of the hype. They could care less about the team. They would rather be there for the beer and food and also to be seen on television. They also like to get really hype during the after party. You know the type. Once the game is over, they let loose and are usually as loud as you can be and they cheer for hours just to say they were there and more than likely are extremely wasted. This though is a fan, so if they are there at least they make us feel at home. Some like to label this type to the Bleacher Bums of Wrigley Field.
5. Location Fans - Similiar to the regular fans but slightly different. This also applies to many different clubs and sports. The Location fan is simply a fan who cheers for the home team. No matter what sport it is. If the game is on and the team from their state or city is playing they cheer for that team. Enough said.
6. Fair Weather Fan - Again, applies to all sports. Now this one is not something to be proud of in my book but, it is very common to see these people. This type of fan you only see when the team is winning or performing well. Again, simply put, enough said.
7. The Diehard Cubs Fan - This type of fan is the coolest to be. But please, Do not try to be this kind unless you truely are one at heart. This fan is the guy who literally knows everything about the team and the history of the team. They own T-Shirts, Hats, Coats, License plate covers, have stickers on their cars, computer desktop screens, beer cozys, and even the occasional pair of boxers with the logo of their team on them. This person has grown up a fan of this team and will always cheer for this team. Through thick and thin they cheer on their team. (This includes bad weather for real). Even through 100 year droughts without a World Series Championship, they root for their team. This type of fan will know when players and owners do something even during the offseason. This type of fan is the guy who refers to the team as "WE". You know this type. They will say things like "WE need to win the next two games or else." even though they are only cheering them on, not actually playing. I consider myself one of these types of fans. Just don't mistake these fans for the Stupid Fans. (I should not even have to explain that one. You already know who I'm talking about)

This is me trying to convert a Cardinals fan on the left to a Cubs fan. Looks like I am doing a pretty good job.
Lastly
8. The Fake Fan - Now this is a combination of the Fair Weather Fan and someone who wants to be cool. This no good person type fan is someone who again notices that a team is doing good they begin to cheer for that team. Suddenly they seem to know everything about that team even though they really don't. They can be identified very easily though. LOL
A few things to look for when hunting for Fake Fans. One... They might have a slightly slower get hype feeling. For instance, the game is tied and a call is made and it is obviously a bum call. Once everyone else begins to complain and talk about this bum call they come in behind and say the same things and complain, but you have to wait for that delayed reaction before you call them a fake fan. Two... They show up late to a game and ask what is going on. Sometimes they will ask what period it is when the sport you are watching is Baseball or other stupid questions. Again, please wait until this stupid question is thrown out there to judge them on being fake. Otherwise it might just be a true fan that was held up at work. Again make sure that stupid question is thrown out before judgement. Lastly... There is always the guy that wants to go out with people and be cool. You ask him to go watch the game and he could care less about the game. When you tell him you are going to watch the game at the bar. He then asks "Sweet, what time and who are they playing?" Now this guy is hard to catch, but if you pay attention he possesses both of the first two traits but just holds back and really doesn't posses any enthusiasm towards the sport.
This is the fake fan. If anything, try not to be the fake fan. Be yourself and just say "Dude I don't care who wins, I just want to drink some beer" Fess up and we will not hold it against you.
Well there you have it. !!! THE FANS !!!
Without fans there would be no sports. I mean how would these multimillion dollar players make money with the absence of fans. So, no matter what type of fan you are, please know what type you are and don't be a fan you are not.
Later,
GO CUBS GO !!!!!
