A general term for someone who carries out actions with such stupidity that they might as well wear their ass as a hat.
Pete begins looking for his sunglasses, unknowing to the fact that they are on his head. He asks Ed where his glasses are. Ed takes them off his head saying, "You are such a fucking ass-hat."

What I type in google to see if I have internet. Usually done if my wireless network takes a shit and I have to search something random to ensure I do not get a cached page.
Unplug the router, plug it back in, head to firefox and type in ass hat to make sure everything is back online.

Although the standard definition is one who has their head so far up their ass that they may as well be wearing their ass as a hat. I also like to imagine it as being someone being so useless that they are just as or moresoe useless as a hat that you wear on your arse. obviously nudist may disagree and wouldnt mind saving their asses from sun burn, but to them i say; your not a real nudist!
