The idiom is applied to a person who has more or less vegetated into maturity and old age and who, already far past his prime, suddenly tries without success to do all the things he might have done when younger. It may be used with reference to an elder who tries to be a dandy.
The native duck, debar, doesn't fly very well, or high like other birds, it doesn't walk or run like some animals, it can't sing well, and it doesn't swim as well as a fish. But it can do all these things. Applied to a person who seemingly can do many different things, none of them expertly. "Jack of all trades."
