Between 2006 & 2009 I wrote comments on this Mudcat thread and at least one other Mudcat discussion thread* asserting my belief that the 1970s African American vernacular phrase "ah sookie sookie now" derived from either the nickname "Sukey" or the Spanish word "azucar" (in English "sugar"), or the Akan [West Africa] female day name "Akosua" (girl born on Sunday).

*http://mudcat.org/thread.cfm?threadid=91272 "Say what?-song lyrics defined."

With the exception of the indirect connection of the term "sukey jumps" to the nickname/name "Sukey", I retract those other assertions.

I now believe that "sukey jumps" was likely the source of "ah sookie sookie now". When I wrote those comments I wasn't familiar with the term "sukey jumps". Also, I mistakenly thought that the word "sukey" in "sukey jumps" was pronounced "SUE key".

That said, I still believe that the Spanish phrase "suca suca"* derives from the Spanish word "azucar" and I believe that the phrase "suca suca" that is found in Zap Mama's rendition of "Iko Iko" at least derives from that Spanish phrase, although it may also have the same meaning or a similar meaning as "ah sookie sookie" (an informal expression that indicates approval of the way a person's body looks).   

*The beginning syllable in the word "suca" in "suca suca" also rhymes with the word "look".
