"My friend is composing an epic in Byronic stanzas entitled 'True History of Autua, Last Moriori'"

Also known as ottava rima, the Byronic stanza pre-exists Byron by a few hundred years. It is described in the Penguin Dictionary of Literary Terms as 'An eight-line iambic stanza ryhming abababcc'. As used by Byron, the rhyming couplet at the end of the stanza would often be comic in tone.
