Answer: idiom
Step-by-step explanation:
Saying that something separates the men from the boys is an idiom used to say that an event or experience distinguishes those who are experienced, skilled, or powerful from those who are not.
An idiom is a figure of speech that uses a commonly known phrase or saying that represents something entirely different from what is being said. Another example would be "under the weather," which is a common saying for when someone is feeling sick.
