I can take you places you ain't never been before
Baby take a chance or you'll never ever know
I got money in my hands that I'd really like to blow
Swag swag swag, on you
Chillin by the fire while we eatin' fondue
I dunno about me but I know about you
So say hello to falsetto in three two swag
I'd like to be everything you want
Hey girl, let me talk to you
If I was your boyfriend, I'd never let you go
Keep you on my arm girl, you'd never be alone
I can be a gentleman, anything you want
If I was your boyfriend, I'd never let you go, I'd never let you go
Tell me what you like yeah tell me what you don't
I could be your Buzz Lightyear fly across the globe
I don't ever wanna fight yeah, you already know
Imma make you shine bright like you're laying in the snow, burr
Girlfriend, girlfriend, you could be my girlfriend
You could be my girlfriend until the epic world ends
Make you dance do a spin and a twirl
Voice goin crazy on this hook like a whirl wind
Swaggie
I'd like to be everything you want
Hey girl, let me talk to you
If I was your boyfriend, I'd never let you go
Keep you on my arm girl you'd never be alone
I can be a gentleman, anything you want
If I was your boyfriend, I'd never let you go, I'd never let you go
So give me a chance, 'cause you're all I need girl
Spend a week with your boy I'll be calling you my girlfriend
If I was your man, I'd never leave you girl
I just want to love you and treat you right
If I was your boyfriend, I'd never let you go
Keep you on my arm girl you'd never be alone
I can be a gentleman, anything you want

译文
若我是你的男朋友，我绝不会让你离我而去
我可以带你去你从来都没有去过的地方
亲爱的，为什么就不给彼此的一个机会呢
没有你即使我有再多的钱也没用
与你相比，那是一文不值的
即使再大的考验我们也能解决
为了你我可以忘记自己的姓名
可以先过来互相打声招呼吗
我可以做到你想要的一切
嘿 女孩，我可以跟你说几句吗
若我是你的男朋友，我绝不会让你离我而去
你若是在我身边，我绝不会让你感到孤独
我可以为你做到千依百顺，满足你的一切要求
若我是你的男朋友，我绝不会让你离我而去， 我绝不会让你离去
告诉我你的喜恶
