There are many occasions which might cause you to shout this - a burglary, a bedroom floor, a naughty puppy. But for the Anglo-Saxons, who had much less stuff than us to worry about, there was only one cause: pigs!
Indeed! A Pigsty!
Try shouting that in anger and see if it makes you feel better.

Disclaimer: these pigs are actually probably quite tidy
