Greenlandman’s Galley
.The lowest type of profanity and vulgarity.
“In my seafaring days the Greenland sailors were notorious for daring and their disrespect of speech, prefacing or ending every sentence with an oath, or some indecent expression. Even in those days [the first quarter of the nineteenth century] a ‘Greenlandman’s Galleyʹ was proverbially the lowest in the scale of vulgarity.”—C. Thomson: Autobiography, p. 118.
