Glass jaw
Meaning
A glass jaw refers to a person or entity that is easily defeated or highly vulnerable to attack.
Origin
In the brutal world of boxing, a fighter with a "glass jaw" is a tragic figure—a pugilist whose chin, no matter how skilled or powerful the rest of their body, seems impossibly fragile. The vivid metaphor evokes the image of a jaw literally shattering like glass under the force of a punch, instantly incapacitating the fighter. This term emerged from the ringside vernacular of the 20th century, describing boxers who, despite their strength or technique, were prone to quick knockouts, making them a vulnerable target for any opponent skilled enough to land a solid blow to the chin.
Examples
