Motorcycle Repair: Harley Question, southside johnny, hand signs

Question
Alright here goes nothing;
Define a Biker, just the basic in's and out's of them.

As for bikes, are they mainly a cruising bike like Harley Davidson's or sport bikes as well?

Describe the clubs and groups that bikers are in or associated with.

Explain all the regional events and what goes on in them.

Any requirements to be a biker, or be accepted into a group?

Is the Badass, Barfighting, Leather Jacket and chaps who walks into a bar and carries a lady out over his shoulder and if you look at him wrong, you better say goodnight pal (a bit long winded) steriotype true?

I am just throwing these out in hopes that you elaborate...and you do not need to follow it question by question, Im really just looking for it all, the big things even down to the hand signs when you ride past another guy on a Harley. You have free rein on it, all I hope you do is goto town with explaining it all...uncensored, the nitty gritty.

And if you have the time tonight to do it, it is almost needed but if not youre still helpin so much.

Hope to hear from ya tonight -Adam

Question -
This is less about anything technical on the workings of a bike and more about the culture.
I am writing a paper for my English class and I chose to focus on the culture around bikes, more or less Harley Davidson and bikers. I know there really is not anyone I can ask on here but if you know the ins and outs of it, and maybe presuably and hopefully are a biker yourself (I may be going out on a limb, and if so I appologize). But if you are, I would love your comments on a battery of questions that I can use to write a stronger paper.
If you can help me out, just email me whenever and I will be more than thankful to send the questions to you, I will be sitting around the computer all day studying anyway

Thanks a Million
Adam
