look up any word, like ratchet:
1. ice cream from heaven
2. the smoothest sleeping material made to man
3. sperm, sticky penis juice

1. When you eat a ZESTO you can't help but stick the whole thing in your mouth! You can't lick it, you have to kinda suck it.

2. I would love to sleep in a pool of ZESTO tonight with a blanket of in-between-the-fingers-skin. That would be satisfying.

3. I don't really like the taste of ZESTO because it is often too sticky and juicy.

A mixture of pesto and zucchini that is put on top of food and drinks for flavor and decoration.
I love to put zesto on my pasta.
