When a person is charged with some type of crime but is not convicted or punished for it, some people might say he was acquitted. In many cases, however, people use idioms, which are non-literal expressions, to describe such situations. In this instance, people may say the person beat the wrap, which means the same thing as acquitted and just represents a more colorful way of saying the person escaped related punishment. This idiom is typically used when speaking of someone who was accused of or charged with a crime. In some situations, however, a person may also use it to describe a situation in which a person escapes some other type of punishment.
Typically, if a person commits a crime and is caught or turns himself in to law enforcement officials, he has a trial and is either convicted or acquitted. If he is convicted, he faces some sort of punishment, which often includes time spent in prison. If he is acquitted, on the other hand, this means he escapes punishment. An individual may describe the outcome of such a case by stating that the person was acquitted or found not guilty of the charge. To use a more colorful way of saying the same thing, however, an individual may state that the accused party beat the rap.
Though the phrase "beat the rap" is typically used in discussions about a person who avoided punishment for a crime, there are other ways to use the phrase. For example, if a child avoids getting grounded, his friends may say he beat the rap. Likewise, if parties are accused of wrongdoing at work and some of them escape work-related punishment, they may be described as beating the rap as well.
The phrase "beat the rap" is an idiom, and like other idioms, it is a way of expressing oneself and is not meant to be taken literally. Most regions have idioms that are commonly used by people in the same region. As such, people who live in a region in which an idiom is commonly used don't normally need help with understanding what it means. Idioms such as "beat the rap" can prove confusing for people who are not from the same area and have never heard or used them, however. For example, if an individual visits a foreign country, he may have a difficult time deciphering commonly used idioms.
