Bottling is when a concert audience throws various objects at the performers onstage. This generally happens at festivals when one act in the lineup is of a different genre or audience than the rest of the bands, especially festivals where the majority of bands are related to heavy metal and punk rock music styles.[1]
While bottling generally involves empty or full bottles of water, it is also common for bottles to contain urine. Other items such as garden furniture, mud, fireworks, broken glass, and dead animals have also been recorded as thrown items.[1]
During a Smiths concert in 1987, singer Morrissey was bottled and pleaded to the crowd: "At this moment we would like to ask all the journalists in the audience to please stop throwing things!"
