Long ago, Tantalus turned into a verb: if something tempts you but you’re never allowed to have it, it is tantalizing you. Well, I hereby declare the verbing of Sisyphus, henceforth to be used for tasks which undo themselves every time you finish them.
As you might guess, this is because I’m being sisyphized by something right now. And not just in the usual laundry-and-dishes sense.
(Ixionizing, I suppose, would be when something goes round and round without ever getting anywhere at all, like a hamster on a wheel. Or, well, Ixion. On his wheel.)
