Booing
From Simple English Wikipedia, the free encyclopedia
Booing means shouting "BOO!" If people shout "boo" after a performance (e.g. a concert, play or opera) they are showing that they did not like it. It is really the opposite of applause (clapping to show that the performance was good).
Booing and hissing used to be very common, especially at the opera. This is not surprising because, in the early days of opera (from the 17th to the early 19th century) opera audiences often behaved badly. They went, not to listen carefully to the music, but to chat to their friends and to cheer their favourite singers and to boo the other singers who were their rivals.
Booing is not very common nowadays in Western culture because people think it is rude. Audiences today are more likely simply not to clap if they do not like a performance. Slow hand-clapping is also a way of showing displeasure.
