Did I really just forget that melody?

When I popped off, then your girl gave me just a little bit of lockjaw
Baby so cold, he from the north, he from the Canada
Bankroll so low, I got nothing else that I can withdraw
Ran out the door
I shine my wrist, it go like shashasha, shashasha
I got your bitch singing, "Lalalala, lalala"
I shine my wrist, it go like shashasha, shashasha
I got your bitch singing, "Lalalala, lalala"

How I stride like that?
Amex, no cap, eight hundred score
They wonder how, how I guap like that
I rap my lyrics when I perform
They wonder how

I shine my wrist, it go like shashasha, shashasha
I got your bitch singing, "Lalalala, lalala"
I shine my wrist, it go like shashasha, shashasha
I got your bitch singing, "Lalalala, lalala"
