World's Best Ex-Girlfriend

All of your friends say they're gonna miss me
Even your mom says she would've picked me
If she didn't have a stupid son
I probably would've been the one
'Cause if I'm a 10, you're a 5 on a good day
Never even thought you were hot in the first place
I gave your ugly ass a chance
'Cause I thought you were a better man

I'm not there, but I'm not gone
Good luck moving on, 'cause, baby

I'm the world's best ex-girlfriend
Oh, you're never gonna forget me
Until we're both dead
Oh, you know I'm gonna haunt your dreams
Wherever you go, I'll be in your head
Making sure you never fall in love again
World's best ex-girlfriend

I'm the one that got away, I'm your worst regret
When you add a double Ts, that's a triple threat
Now every girl you ever date is sleeping in the bed I made

'Cause I'm not just funny, I'm smart and hot
Just look what you lost, 'cause, baby

I'm the world's best ex-girlfriend
Oh, you're never gonna forget me
Until we're both dead
Oh, you know I'm gonna haunt your dreams
Wherever you go, I'll be in your head
Making sure you never fall in love again
World's best ex-girlfriend

I can do better, that's a fact
If you thought you'd do better, you're a maniac
This song's so catchy
If you hear it on your radio, I hope you crash

I'm the world's best ex-girlfriend
Oh, you're never gonna forget me
Until we're both dead
Oh, you know I'm gonna haunt your dreams
Wherever you go, I'll be in your head
Making sure you never fall in love again
