Okay, I believe taht the meaning of "spliced" and "whack" and maybe even "Hilo" has been solved [and maybe not].

And Crane Driver's comment made me think of this expression that means something different than it means in its literal sense:

"Ah, Sukey Sukey! {also given as "Ah Sukey Sukey now!"}

"Sukey" is a diminutive form of the female name "Susan". However, at least in the United States, that nickname is seldom used anymore.
I believe that the phrase "Ah, Sukey Sukey!" came from that nickname
but has nothing to do with any female name. Instead, it is an expression of approval for a woman's sensual appearance or seductive dance movements. In that sense, "Sukey" borrows some of the coded meaning the somewhat similar sounding word "suck", though
sukey, or sookey is pronounced "SUE-key".

I've heard this expression spoken by men as an expression of the way a woman looks. Here's an example of the use of this expression in a 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.
You make me feel good inside.
Come on, and groove me, baby.
I need you to groove me.
Ahhh, yeah, now, now, darling.
Uhh! Come on, come on!
Hey! Uhh!
Hey there, Sugar Darlin',
Come on, give me something
Girl, I've been needing for days.
Yes, I'm good, good loving,
With plenty, plenty hugging.
Ooh, you cute little thang, you.
Girl, between you and me, nah-nah,
We don't need no company.
No other man, no other girl
Can enter into our world,
Not as long as you groove me, baby.
Ahh, come on.
Make me feel good inside.
Come on and groove me, baby.
Move me, baby.
Ahh, sock it to me, mama.
Uhh! Ahh, I like it like that, baby.
Uhh! Groove me, baby! Hey! Uhh!
Groove me, darling!
Come on, come on.
I need you to sock it to me, mama.
Come on and groove me, baby.
Hey! Uhh! Good, God!
It makes me feel so good inside, mama.
Now, come on, come on, and uhh,
Groove me, baby, groove me, baby.
Ahh, sock it to me,
Sock it to me,
Rock it to me.

Less frequently, I've also heard "Ah Sukey Sukey, now" used as a more generalized expression of approval for something someone has said that was particularly daring, for instance a statement that is not at all cautious or nicey nicey but one that might cause folks to "get right down to the real nitty gritty" of a matter.
