I prefer chicks who are leveled: not too extreme, on way or the other.
For example: Some guys like crazy chicks who say things like, "You ever wonder what it would be like to bang yourself in the future", while others prefer laid-back chicks who say things like, "I love the sensation of a warm breeze while I lie in a field of soft grass".
Me, I want the chick who says, "Man, that warm breeze feels great today and is giving me all kinds of ideas. Hey... you ever have sex in a field before?"
You know where that convo ends up :P
