ACID-2.html - noun
( Music ) (Youth Culture) A style of popular music with a fast beat, a spare, mesmeric, synthesized sound, few ( if any) vocals, and a distinctive gurgling bass; in the UK, a youth cult surrounding this music and associated in the public mind with smiley badges, drug-taking, and extremely large parties known as acid house parties. Sometimes abbreviated to acid (also written acieeed or aciiied, especially when used as a kind of interjection ). Etymology: The word acid here is probably taken from the record Acid Trax by Phuture ( in Chicago slang, acid burning is a term for stealing and this type of music relies heavily on sampling, or stealing from other tracks); a popular theory that it is a reference to the drug LSD is denied by its followers (but compare acid rock, a sixties psychedelic rock craze, which certainly was). House is an abbreviated form of Warehouse: see house . History and Usage: Acid house music originated in Chicago as an offshoot of house music in 1986; at first it was called 'washing machine', which aptly described the original sound. Imported to the UK in 1988, acid house started a youth cult during the summer of that year, and soon spawned its own set of behaviour and its own language. The craze for acid house parties, at venues kept secret until the very last moment, exercised police forces throughout the south of England, since they often involved trespass on private land and caused a public nuisance, although organizers claimed that they had been maligned in the popular press. I suppose that a lot of acid house music is guilty of...being completely cold and devoid of any human touch. Spin Oct. 1989, p.

ACID-2.html - Rain containing harmful acids which have formed in the atmosphere, usually when waste gases from industrial emissions combine with water. Etymology: Formed by compounding: rain with an acid content. History and Usage : The term acid rain was first used as long ago as 1859, when R. A. Smith observed in a chemical journal that the stonework of buildings crumbled away more quickly in towns where a great deal of coal was burnt for industrial purposes; this he attributed to the combination of waste gases with water in the air , making the rain acidic. In the early 1970s the term was revived as it became clear that acid rain was having a terrible effect on the forests and lakes of North America, Europe, and especially Scandinavia (killing trees and freshwater life). Acid rain started to be discussed frequently in official reports and documents on the environment; but it was not until environmental concerns became a public issue in the eighties that the term passed from technical writing of one kind and another into everyday use. With this familiarity came a better understanding of the causes of acid rain, including the contribution of exhaust fumes from private vehicles. By the end of the eighties, acid rain was a term which even schoolchildren could be expected to know and understand, and had been joined by variations on the same theme : acid cloud, a term designed to emphasize the fact that acidic gases could damage the environment even without any precipitation; acid fallout, the overall atmospheric effect of pollution; acid precipitation , the name sometimes used for snow or hail of high acidity. She has a list of favorite subjects, favorite serious subjects--nuclear proliferation, acid rain, unemployment, as well as racial bigotry and the situation of women.
