I was going to add that when I'm pissed I'm not very articulate ... and then I realised Jon was talking about angry rather than drunk ... and then I thought, I'm often not very articulate when I'm angry either.
... And then I read the previous paragraph and thought, maybe I'm just not very articulate.
All of which supports the idea that such a curse needs to be short and sharp - and easy to say when you're pissed in either senses of the word. There are other forms of cursing, it doesn't always require anger and/or inebriation, and if that was the case then something more elaborate could still fit.
