greeks look down upon...

[FuzzieAlum]

I don't think there's much of anything that Greeks as a whole look down upon, with a few big exceptions (murder, for example, or being out and out racist). But each chapter will have different ideas of what they want in a girl. Chapter A may say, "She dresses too slutty," and B will say, "Oh! She's so cute!" Or C likes girls who party, and D doesn't.

So assuming your wild stuff is (mostly) on this side of the law, excluding a little partying, you should be fine! If you're outgoing, you'll just naturally find the chapters that suit your personality.
