The Boy Who Cried Fabulous by Lesléa Newman
Plot Summary: The only thing Roger likes better than exploring the world around him is describing it. And Roger describes most things as fabulous! But his parents have a different view. They want Roger to see things the way they do, so they ban "fabulous" from his vocabulary. Fabulously illustrated by Peter Ferguson, this cheerful tale will have children rejoicing along with Roger at all the fabulous--no, marvelous! no, dazzling!--things that await him when he steps outside.

Other than the fact that fabulous is a word we’ve coded to indicate a gay man, there’s nothing particularly queer about this book. Also, his parents are objecting to the way Roger gets distracted and is therefore late to school, not really the word fabulous in and of itself. Cute story by the author of Heather Has Two Mommies, and can be a good opportunity to talk about assuming things based on the way someone speaks.
