The original song is called "Breakfast in America" and was from the album of the same name. FallOut Boy is either doing a kind of "homage" or else they are mocking it, in the video in Gym Class Heroes - Cupid’s Chokehold... In fact the "ba-da-da-da" is actually a sample from the Supertramp song... and many of the lines are actually lifted - almost whole although they seem intentionally twisted a bit, so I'm not sure if it should really be considered a new original song based on the old one or a pop reference to Supertramp or sort of a parody. I leave it to you to decide for yourself.
For comparison: The original
Breakfast in America by Supertramp (1979) 2:39

Take a look at my girlfriend
Shes the only one I got
Not much of a girlfriend
Never seem to get a lot
Take a jumbo across the water
Like to see America
See the girls in California
I'm hoping its going to come true
But theres not a lot I can do
Could we have kippers for breakfast
Mummy dear, mummy dear
They got to have em in Texas
Cos everyones a millionaire
I'm a winner, I'm a sinner
Do you want my autograph
I'm a loser, what a joker
I'm playing my jokes upon you
While theres nothing better to do
Don't you look at my girlfriend
She's the only one I got
Not much of a girlfriend
Never seem to get a lot
Take a jumbo cross the water
Like to see America
See the girls in California
I'm hoping its going to come true
But theres not a lot I can do
and Fallout Boy: Gym Class Heroes - Cupid’s Chokehold

Take a look at my girlfriend
She's the only one I got (ba ba da da)
Not much of a girlfriend
I never seem to get a lot (ba ba da da, ba ba da da)
It's been some time since we last spoke
This is gonna sound like a bad joke
But momma I fell in love again
It's safe to say I have a new girlfriend
And I know it sounds so old
But cupid got me in a chokehold
And I'm afraid I might give in
Towels on the mat my white flag is wavin'
I mean she even cooks me pancakes
And Alka Seltzer when my tummy aches
If that ain't love then I don't know what love is
We even got a secret handshake
And she loves the music that my band makes
I know I'm young but if I had to choose her or the sun
I'd be one nocturnal son of a gun
(ba ba da da, ba ba da da)
Take a look at my girlfriend
She's the only one I got (ba ba da da)
Not much of a girlfriend
I never seem to get a lot (ba ba da da, ba ba da da)
Take a look at my girlfriend
She's the only one I got (ba ba da da)
Not much of a girlfriend
I never seem to get a lot (ba ba da da, ba ba da da)
It's been awhile since we talked last and I'm tryin' hard not to talk fast
But dad I'm finally thinkin' I may have found the one

Type of girl that will make you way proud of your son
And I know you heard the last song about the girls that didn't last long
But I promise this is on a whole new plane
I can tell by the way she says my name (ba ba da da)
I love it when she calls my phone
She even got her very own ringtone
If that ain't love then I don't know what love is (ba ba da da)
It's gonna be a long drive home but I know as soon as I arrive home
And I open the door take off my coat and throw my bag on the floor
She'll be back into my arms once more for sure
Take a look at my girlfriend
She's the only one I got (ba ba da da)
Not much of a girlfriend
I never seem to get a lot (ba ba da da, ba ba da da)
She's got a smile that would make the most senile
Annoying old man bite his tongue
I'm not done
She's got eyes comparable to sunrise
And it doesn't stop there
Man I swear
She's got porcelain skin of course she's a ten
And now she's even got her own song
But movin' on
She's got the cutest laugh I ever heard
And we can be on the phone for three hours
Not sayin' one word
And I would still cherish every moment
And when I start to build my future she's the main component
Call it dumb call it luck call it love or whatever you call it but
Everywhere I go I keep her picture in my wallet like here
Take a look at my girlfriend
She's the only one I got (ba ba da da)
Not much of a girlfriend
I never seem to get a lot (ba ba da da, ba ba da da)
Take a look at my girlfriend
She's the only one I got (ba ba da da)
Not much of a girlfriend
I never seem to get a lot (ba ba da da, ba ba da da)
