Fungible

I was talking to some friends yesterday, and the word "fungible" came up. I said that I love my two cats, but that they are fungible, so if they were to lose them somehow, I would replace them with other pets with whom I could give my love to.

Nobody seemed to understand exactly what fungible meant. Is it really that nerdy of a word? I thought it was pretty normal.

In case you are wondering, Miriam-Webster defines fungible as:

fungible
adjective
1 : being of such a nature that one part or quantity may be
replaced by another equal part or quantity in the satisfaction of an
obligation. e.g. oil, wheat, and lumber are fungible
commodities.
2 : interchangeable.

So my challenge to you is to use the word today in conversation. Go ahead. Don't be scared. Let's all sound educated together! :-D
