I'm certainly no expert, but here is what I find with my difficult child: she is like any other teenager that is "defiant" but she takes it to extremes. Everything is a fight with her beacuse she is going to get the last word in no matter what, she will make excuses for EVERYTHING to include why she didn't close up the cereal box, she will walk over the same piece of junk on the floor for days until told to oick it up and then there is a great deal of whining and complaining, she throws "fits" if not allowed to go out with friends or be in a situation that I don't approve of. During these fits she has broken almost every piece of glass in the house (we buy plastic stuff now!), she makes obnoxious rude comments to us and her friends consistently to the point they all call her "mean" - when confronted about the "mean" comments she looks at me with a straight face and says she doesn't care. Just a general view of what ODD is like in our house - again - I'm no expert, but I do know what we live with.
