There's a discussion on this
Mudcat thread about different meanings and [perhaps different origins] of the word "Sukey".

Lyle's Oct 31 2000 statement that [sookie/sukey] "Huddie thought, was derived from the field term for a cow, and was used to call a cow". A poster in that linked thread always said that 'sukey' was used to call cows. Another poster said that 'sukey' was a colloquial expression in Canada for a sensuous woman. And I noted that "Sukey" is a nickname for "Susan" and may have also come from the Akan {Ghanaian} female name "Akosua". I also mentioned that the colloquial African American phrase "Ah Sukie Sukie now" was {and I believe still is} sometimes used by men as approval for a sexy woman's body or as approval for a sensuous dance move that a woman makes.

An example of that last use is found in this R&B song:

GROOVE ME {Artist: King Floyd}
Uhh! Awww, sookie sookie now!
Hey! Oww, uhh! Come on, baby!
Hey there, Sugar Darlin',
Let me tell you something
Girl, I've been trying to say, now.
You look so sweet,
And you're so doggone fine.
I just can't get you out of my mind.
You've become a sweet taste in my mouth, now.
And I want you to be my spouse,
So that we can live happily, nah-nah,
In a great big ol' roomy house.
And I know you're gonna groove me, baby.
Ahh, yeah now...

I suppose this may have something to do with "sukey jumps".

But maybe not.
