obtainium
anything you get for free, whether you begged, stole it, or it fell out of someone's pocket while they were distracted.
I got a free bagel from the guy who dropped it on the sidewalk. It was obtainium. And I ate it. And I felt rich.
My mom gave me her old socks. That's obtainium. And I made a sock monster. And it was terrifying.
I got a free shirt from a donation bin. It's obtainium. And it smells like someone else's regret.
