[Verse 1]
You made your way in as I was leaving
You cut in line just as I was getting my stuff
And I couldn't decide if you were the most annoying human being I'd ever met
Or just the best thing that ever happened
Just the best thing that ever happened

[Verse 2]
You took the key out of the ignition
I could hear the rain on the windows
Right then and there, I made up my mind to just go with it
Thinking, "What's the worst thing that could happen
When the worst thing that could happen could be the best thing ever?"

[Refrain]
We're not forever, you're not the one
We're not forever, you're not the one
We're not forever, you're not the one
You and I could be the best thing ever

[Pre-Chorus]
We're not "happily ever after," we don't got what it takes
And we don't make plans 'cause we're never gonna last
We're not forever, you're not the one

[Chorus]
You and I, we're a timebomb, bomb, bomb, bomb
Bomb, bomb, bomb, bomb
We're not forever, you're not the one
You and I, we're a timebomb
[Verse 3]
I shut the door and I don't look back
When something this good comes along
You're better off letting the first time be the last time
But really, what's the worst thing that could happen
When the worst thing that could happen could be the best thing ever?

[Refrain]
We're not forever, you're not the one
We're not forever, you're not the one
We're not forever, you're not the one
You and I could be the best thing ever

[Pre-Chorus]
We're not "happily ever after," we don't got what it takes
And we don't make plans 'cause we're never gonna last
We're not forever, you're not the one

[Chorus]
You and I, we're a timebomb, bomb, bomb, bomb
Bomb, bomb, bomb, bomb
We're not forever, you're not the one
You and I, we're a timebomb

[Bridge]
Ooh
We could be the best thing ever
Oh, we could be
We could be the best thing ever
The best thing ever
We could be the best thing ever, ooh
Forever
We could be the best thing ever (Oh, we)
We're not forever (Could be)
You're not the one (The best)
[Chorus]
You and I, we're a timebomb, bomb, bomb, bomb
Bomb, bomb, bomb, bomb
We're not forever, you're not the one
You and I, we're a timebomb
