The phrase "crock up" is a less common expression that can mean to suffer a nervous breakdown or to reach a point of extreme stress where a person cannot cope anymore. It is often used informally and can sometimes imply that someone is overwhelmed by their emotions or circumstances.
In advanced contexts, you might see "crock up" used in discussions about mental health, stress management, or the pressures of modern life.
While "crock up" primarily refers to a nervous breakdown, it can also be used in a broader sense to describe situations where someone is overwhelmed and unable to function effectively.
If you or someone you know is feeling overwhelmed and "crocking up," it is important to seek help or talk to someone about it.
