Man up, man up (yeah)
Little boy, won't you man up?
Man up, man up (yeah)
Little boy, won't you man up? (Okay)

My brother hates you, my mother hates you
My father and sister, too
Wait, I don't even have a sister
But if I did, she'd hate you
Everything is in past tense
'Cause we're definitely more than through
And I'm runnin', runnin', runnin'
Runnin' out of ways to get through to you

I think it's cute that
Look me in the eyes, won't do that (woo)
Six knives in my back
Tell me why you would do that (do that)
Sun goes down, different face
Didn't think I'd learn her name
Gave you every bit of trust
I just can't believe you'd abuse that

Man up, man up (yeah)
Little boy, won't you man up?
Man up, man up (yeah)
Little boy, won't you man up?
All of these tantrums
They won't win me back, love
Just be a man, love
And I don't mean to sign this version
I just mean, be a better person
For once, man up (okay)

If you would've taken accountability
Then you'd still be holdin' my hand
Maybe not as tight, but at least maybe
Maybe you'd have a chance
I don't even wanna keep talking about this
So I'll just stop
Sike, thought I was done but I'm not (done but I'm not)

I think it's cute that
Look me in the eyes, won't do that (do that)
Six knives in my back
Tell me why you would do that

Man up, man up (yeah)
Little boy, won't you man up?
Man up, man up (yeah)
Little boy, won't you man up?
All of these tantrums
They won't win me back, love
Just be a man, love
And I don't mean to sign this version
I just mean, be a better person
For once, man up (okay)

Ooh, yeah, yeah, yeah, yeah
Ooh, yeah, yeah, yeah, yeah

Man up, man up (yeah)
Little boy, won't you man up? (Won't you man up?)
Man up, man up (yeah)
Little boy, won't you man up?
All of these tantrums
They won't win me back, love
Just be a man, love
And I don't mean to sign this version
I just mean, be a better person
For once, man up (okay), yeah

Just be a man, you baby
I'm done (okay)
