fibbery

To me, his facility with fallacy and his pain-free fibbery aren’t symptomatic of a liar but of a madman.

That already egregious example of gross fibbery has, implausibly, been supplanted by an even larger whopper.

The fakement conn'd by knowing rooks Must be well known to you, And if you come to fibbery,   You must mug one or two.

I like the Irish but his cheerful fibbery was the last straw and I went home.
