A character who is often a Large Ham or a Small Name, Big Ego will often brag about how no one or nothing is better than he is. Unfortunately, just as soon as he says this, another character tells him that the boss wants to have a word with him about his lack of progress. As a result, the braggart literally shrinks in shame because of this.
Put more simply, this is when a character literally shrinks when either embarrassed, ashamed, or humiliated about something. In a fantasy setting, they may truly be becoming smaller, but in other places it's just a visual shorthand. Expect this to show up very often in Comedy or Western Animation.
Not to be confused with feeling embarrassed about unwanted shriveling of the male genitals.

François Mitterrand: [takes a deep breath] Because you look full of yourself, pedantic and contemptuous; you constantly show the arrogance of a peacock; you are distant with the people and puffy with pride; you parade at the smallest success and are petrified with fear at the smallest breeze; the polls made you presumptuous, and you so much wanted to be unavoidable that you made yourself unbearable. That's it. Anything else?

Mitterrand: Because thanks to you, Chirac was elected. Dumbass.
