sailor’s blessing
n.— «With flute-and guitar backing from Ryan Driver of Toronto trio Silt, the double meaning of the song’s recurring refrain about “a sailor’s blessing” (a euphemism for a curse) perfectly illuminates the music, no matter what it’s called.» —“The Anti-Hit List for October 21″ by John Sakamoto Toronto Star (Canada) Oct. 21, 2006.
