What does it mean ?

here are the lyrics

My milkshake brings all the boys to the yard,
And their like
It's better than yours,
Dam* right it's better than yours,
I can teach you,
But I have to charge

I know you want it,
The thing that makes me,
What the guys go crazy for.
They lose their minds,
The way I wind,
I think its time

[Chorus x2]
La la-la la la,
Warm it up.
Lala-lalala,
The boys are waiting

My milkshake brings all the boys to the yard,
And their like
It's better than yours,
Dam* right it's better than yours,
I can teach you,
But I have to charge

I can see youre on it,
You want me to teach thee
Techniques that freaks these boys,
It can't be bought,
Just know, thieves get caught,
Watch if your smart,

[Chorus x2]
La la-la la la,
Warm it up,
La la-la la la,
The boys are waiting,

My milkshake brings all the boys to the yard,
And their like
It's better than yours,
Dam* right it's better than yours,
I can teach you,
But I have to charge

Oh, once you get involved,
Everyone will look this way-so,
You must maintain your charm,
Same time maintain your halo,
Just get the perfect blend,
Plus what you have within,
Then next his eyes are squint,
Then he's picked up your scent,

[Chorus x2]
Lala-lalala,
Warm it up,
Lala-lalala,
The boys are waiting,

My milkshake brings all the boys to the yard,
And their like
It's better than yours,
Dam* right it's better than yours,
I can teach you,
But I have to charge
