Booing is a common way for audiences to express dissatisfaction with a performance. It is typically done by making a loud, low-pitched sound (similar to the mooing of a cow) while holding the hands cupped around the mouth to amplify the sound. Booing can be very disruptive to a performance, and it can sometimes lead to the performers being forced to stop.
Throwing Objects
In some cases, audiences may also throw objects at the stage in order to express their dissatisfaction with a performance. This is obviously a very dangerous practice, and it can result in serious injuries to the performers. In some cases, throwing objects at the stage has even led to riots.
Walking Out
Another way for audiences to express dissatisfaction with a performance is to simply walk out of the theater. This is often seen as a more polite way to show displeasure than booing or throwing objects, but it can still be very disruptive to a performance. In some cases, a large number of people walking out of a theater can even lead to the performance being canceled.
Writing Negative Reviews
In the modern era, audiences also have the option of writing negative reviews of performances online. This can be a very effective way to express dissatisfaction with a performance, as it can reach a wide audience very quickly. Negative reviews can also have a significant impact on a performer's reputation and future career prospects.
