Broken; not properly functioning.

Your telly is buggered, best get it fixed.

It's well and truly buggered now; you may as well throw it out.

In trouble; in a bad situation.

Tired, worn-out, exhausted.

You'll have to take over from here, mate, I'm completely buggered.

I am not sure why, but I'm more buggered after I get to the US than I am when I return home. I think it has a lot to do with it being easier to align my sleeping patterns with flying in to Oz during the night (arriving early morning), than it is flying into the US and landing at 10 pm at night.

damned (as an intensifier or vehement denial)

I'm buggered if I'm going to drive all that way at this time of night.
