I have to admit, this was the first time I've ever heard of the term "Zillennial."
To me, it's the second best holiday. It's perfect out, not too cold (where I live), and it's nice to see all the fall decor. I don't ever dress up, I'll just watch some scary movies and eat some candy. I like the marshmallow Kit-Kats the best, though I try to hold off on that so I don't ruin my teeth. :c
