It is claimed that `bogus' was originally used in the hackish sense
at Princeton in the late 1960s. It was spread to CMU and Yale by
Michael Shamos, a migratory Princeton alumnus. A glossary of bogus
words was compiled at Yale when the word was first popularized (see
{autobogotiphobia} under {bogotify}). The word spread into
hackerdom from CMU and MIT. By the early 1980s it was also
current in something like the hackish sense in West Coast teen
slang, and it had gone mainstream by 1985. A correspondent from
Cambridge reports, by contrast, that these uses of `bogus' grate on
British nerves; in Britain the word means, rather specifically,
`counterfeit', as in "a bogus 10-pound note".
