Usage
What does bookworm mean? A bookworm is someone who’s always reading, usually because they just love to read or because they’re studying or both. Bookworm is sometimes used negatively to make fun of people who love to read. But it is more commonly used in a positive way, especially by book lovers proudly calling themselves bookworms. Bookworm can also be used literally as a general name for any insect that eats books. Example: Bookworms usually have huge vocabularies, so be careful when you play one in Scrabble.

Etymology
Origin of bookworm
Explanation
A bookworm is someone who loves to read. If you're a true bookworm, you'd rather spend Friday nights on the couch with a book than out at a party. Some people are bookworms from the moment they first learn to read, while others grow into their love of books and reading after encountering a particularly wonderful book. Even people who didn't love the "Harry Potter" series of books mostly concede that they created a whole generation of bookworms. The word bookworm originally referred to a variety of insects that infest and eat paper, including the pages of books.
