We were definitely something
We are this unlabeled and undefined mess
We had a relationship worth dreaming
There was no 'us' but we had realness

What we had was called almost
We shared what people desire
We tried to last with our outmost
But distance extinguished the fire

We had what some envied
We were perfectly unlabeled and unknown
We were bulletproof but we still bleed
I wasn't yours and I couldn't call you my own

What do I call you, how do I explain us?
You're my ex something, my ex almost, my ex unstable
My ex unnamed, my ex unknown, my ex anonymous
To put it simply, since we are undefined, you are my "x variable"
