:mung: /muhng/ [in 1960 at MIT, `Mash Until No Good'; sometime
after that the derivation from the {{recursive acronym}} `Mung
Until No Good' became standard] vt. 1. To make changes to a file,
esp. large-scale and irrevocable changes. See {BLT}. 2. To
destroy, usually accidentally, occasionally maliciously. The
system only mungs things maliciously; this is a consequence of
{Finagle's Law}. See {scribble}, {mangle}, {trash},
{nuke}. Reports from {USENET} suggest that the pronunciation
/muhnj/ is now usual in speech, but the spelling `mung' is
still common in program comments (compare the widespread confusion
over the proper spelling of {kluge}). 3. The kind of beans of
which the sprouts are used in Chinese food. (That's their real
name! Mung beans! Really!)
Like many early hacker terms, this one seems to have originated at
{TMRC}; it was already in use there in 1958. Peter Samson
(compiler of the original TMRC lexicon) thinks it may originally
have been onomatopoeic for the sound of a relay spring (contact)
being twanged. However, it is known that during the World Wars,
`mung' was army slang for the ersatz creamed chipped beef better
known as `SOS'.
