I think you are talking about the song ' You Know What's Up' by Donnel Jones. Here are the complete lyrics to the song for you:
"Ooh...say what, say what, say what
Ooh...girl, you know what's up
Ooh...say what, say what, say what
Ooh...girl, you know what's up
[Verse 1]
Me and my niggaz be rolling
Trailing on you and your homies
The very first day of summer
All chromed out in a hummer, babe
Hit the park and parlay
Hope that you're off, 'cause you're awake
'Cause you and your girls want to ride
Play all day puff on the lye
[Chorus - Section A]
Ooh...say what, say what, say what
Ooh...girl, you know what's up
(And you know what I need)
Ooh...say what, say what, say what
(You know that I'm bout it, baby)
Ooh...girl, you know what's up
(Ooh...)
[Chorus - Section B]
I'm digging you, I'm feeling you
And you know what's up
Said I'm big on you and I'm wanting you
So tell me what's up
[Verse 2]
We are five when I'm zoning
Running around two in the morning
Looking fly with that sun dress on
I think I feel a bone coming on
Girl, you got me wide open
Fiending all day and I'm hoping
So baby don't front
Backseat jeep, you know what I want
[Chorus - Section A]
[Chorus - Section B]
[Bridge]
Oh yeah, whoa, whoa, whoa...
Digging you, you got me big on you."
[Chorus - Section A]
"Ooh...say what, say what, say what
Ooh...girl, you know what's up
Ooh...say what, say what, say what
Ooh...girl, you know what's up
[Verse 1]
Me and my niggaz be rolling
Trailing on you and your homies
The very first day of summer
All chromed out in a hummer, babe
Hit the park and parlay
Hope that you're off, 'cause you're awake
'Cause you and your girls want to ride
Play all day puff on the lye
[Chorus - Section A]
Ooh...say what, say what, say what
Ooh...girl, you know what's up
(And you know what I need)
Ooh...say what, say what, say what
