How it's used
This idiom uses the imagery of a wax gourd that has rotted inside while the skin remains intact to describe someone who projects an image of competence or intelligence that is entirely superficial. It is a sharp, critical term used to expose someone who is essentially a fraud or an empty vessel. It is most commonly applied to people in professional or academic settings who talk a big game but fail to deliver when pressed for details.
Examples
He is all show and no substance; he goes silent when you ask him a couple more questions.
