A gotcha is a detrimental condition (usually of a contract or agreement) that is designed to sneak past the other party. For example, many "free" Credit Report sites have "gotchas" that automatically sign you up for a monthly credit report service unless you explicitly cancel. "Gotcha" is also a frequently used programming term.----------------Relaxed pronunciation (also called condensed pronunciation or word slurs) is a phenomenon that happens when the syllables of common words are slurred together. It is almost always present in normal speech, in all natural languages (not in some constructed languages such as Loglan or Lojban, which are designed so that all words are parsable).
Some shortened forms of words and phrases, such as contractions or weak forms can be considered to derive from relaxed pronunciations, but a phrase with a relaxed pronunciation is not the same as a contraction. In English, where contractions are common, they are considered part of the standard language and accordingly used in many contexts (except on very formal speech or in formal/legal writing); however, relaxed pronunciation is markedly informal in register. This is also sometimes reflected in writing: contractions have a standard written form, but relaxed pronunciations may not, outside of dialect spelling.-------Pop art is a visual art movement that emerged in the mid 1950s in Britain and in parallel in the late 1950s in the United States. The coinage of the term Pop Art is often credited to British art critic/curator, Lawrence Alloway in an essay titled The Arts and the Mass Media, although the term he uses is "popular mass culture"
