Girl, it's your birthday (Birthday) in here (In here) tonight (Tonight)
Give it to me, go

[Verse 1: Siya, Tank]
Go, go, go, shawty it's your bday
You and your girls takin' shots like a relay
I know y'all only come around when the bottles out
Shit, I only come around when the models out
So-so-so what's your sign, baby?
You a Cancer or Gemini, baby?
You a freak, do you do it for the Vine, baby?
I'm just tryna figure out if we can vibe, baby (R&B money)

[Verse 2: Tank]
I don't wanna waste no time
I just wanna help you celebrate
'Cause I don't meet 'em like you every day
Blow them candles out and get down to the cake
I don't wanna waste no time
Baby girl, I know this what you like
Get it in the air, we can take flight
It's a special day, it's only right, girl

[Pre-Chorus: Tank]
