Azizi, a book you might be interested in is a slave story, "Reminiscences of Isaac and Sukey," by L. C. Capehart, on line at http://docsouth.unc.edu/neh/capehart/menu.html.
Sukey is used among whites as a nickname for Susan, or rarely as a given name, pronounced 'sue-key'. The nickname originated in England, and as posted above, is known in eastern Canada as well as the States. It seems equally popular among African-Americans. The well-known Caribbean children's writer, Sans Souci, has a little girl named Sukey as the main character in a current book.
As a child, I knew a girl nicknamed Sukey (from Susan), and a friend had a mare named Sukey.

Much of the rest here may be duplication and cross-posting, but I hope some will add to what went before.
Hilo, Hawai'i and Ilo, Peru, have caused confusion here before, and the chantey-singers smile knowingly when we make mistakes. Both were important in the days of sail, Ilo for raw materials (and prostitutes ashore) and Hilo for whale rendering, fresh produce, and girls (brown-skinned in both places). The names got mixed up because of their similarity in pronunciation.

Whack has the meaning assigned by Crane Driver, to get my due, and also as a name for savings. Both meanings are found in the Thieves Dictionary of Grose (1780's). Whacked, meaning zonked out or out of one's mind, is not uncommon- don't know its origin.
Splice is a very old north European word. Later, Capt. Smith (1627) in his "Seamans Grammar" described several splices, which are (or were) important to mariners.
The word splice as a reference to marriage is noted in 1830 (OED), but probably it is older.

As noted in another thread, 'cool' is a chameleon, constantly changing popular meaning through time. Chaucer and later Shakespeare used it to mean lack of vitality. Not heated by passion or emotion, unexcited, goes back to Beowulf (A.D. 282 in print). To mean 'assured and unabashed' entered novels in the 1820's with the spy novel of Westmacott. Now it means 'great' or the 'Cat's pyjamas.'
I'm afraid "Our Living Language" lacks any historical perspective on the popular or slang uses of the word.

Azizi, thanks for posting "Groove Me." Hadn't heard that before. Dizzy Gillespie's 'Groove' in the sense of providing pleasure (1945) is quoted in the Oxford E. D. (lyrics to his "Groovin' High."
