This term is rarely used and generally only employed for humorous effect due to the somewhat clumsy reduplication of un-; the first being the adjective prefix un- indicating negation, and the second the verbal prefix un- indicating reversal of an action.

Note that the two prefixes are different in meaning, and therefore this is not a double negative (compare the same construction in un-undoable, which does not mean "doable" but "irreversible").
