D'oh well!
A loud, angry exclamation that happens when you're so fed up that you're ready to scream, but then you just shrug and accept that things are going to stay bad.
D'oh well! I got detention again and I'm gonna be stuck in the hall for the whole day.
D'oh well! My dog peed on my carpet and now I have to clean it.
D'oh well! I lost my keys and I can't get into my house.
