Fib

noun

A lie that has not cut its teeth. An habitual liar's nearest approach to truth: the perigee of his eccentric orbit.

    When David said: "All men are liars," Dave,
    Himself a liar, fibbed like any thief.
    Perhaps he thought to weaken disbelief
    By proof that even himself was not a slave
    To Truth; though I suspect the aged knave
    Had been of all her servitors the chief
    Had he but known a fig's reluctant leaf
    Is more than e'er she wore on land or wave.
    No, David served not Naked Truth when he
    Struck that sledge-hammer blow at all his race;
    Nor did he hit the nail upon the head:
    For reason shows that it could never be,
    And the facts contradict him to his face.
    Men are not liars all, for some are dead.

        Bartle Quinker
