Examples:
* "The teacher gave the student's excuse short shrift."
* "The company's proposal was given short shrift by the investors."
* "The boss gave the employee's complaint short shrift."
Origin:
The phrase is thought to come from the old English practice of "shriving," which was the confession of sins to a priest. To give someone "short shrift" meant that they had very little time to confess their sins before their execution.
