Something that's gooey has a thick, sticky texture.
Imagine you're eating a delicious dessert like caramel or honey. It's hard to describe how it feels without saying it's gooey - it's this weird mix of smooth and rough at the same time. Now, imagine trying to eat something with that kind of texture. Gooey foods are often sweet and tasty, but they can also be a bit tricky to handle. If you get some on your clothes or skin, good luck getting it off! It's pretty common for people to say their favorite snacks are gooey, especially when they're talking about candy or ice cream.
