This thread is meant to be a joke, so don't get all offended about what goes inside it.
Basically, I want to see what all the stereotypes are of everything that has to do with Beta - whether it be the quadra itself, or the different types and aspects that belong within it. So list away! Don't censor yourself.
Oh, and don't forget that the Betas here have the right to debunk any totally false beliefs that you might have. That goes without saying, though.
