Usually, a freak is somebody who does not adhere to societies determined norms. They may be someone who has a different style of thought, dress, or behavior than other people in a given community. Freaks are looked down upon and are rarely accepted by the majority of the population simply because they do not fit in with the rest. Some people believe they are when in reality they are no different than anybody else. In my opinion, everybody is a freak.
Nobody is perfect, and nobody follows all of the rules all of the time.
First of all, if you do something dumb, it is just excused because you are a freak. Of course, you can dress as you wish, think what you want, and be who you really are, without being judged any further. A freak is somebody who is different from you, or is at least perceived to be different. But in reality, they are simply unique in thought and expression. We all have different people whom we consider to be strange, or freakish.
