  From  WordNet  r  1.6  [wn]: 
 
  glitch 
  n  :  a  fault  or  defect  in  a  system  or  machine  [syn:  {bug}] 
 
  From  Jargon  File  (4.2.3,  23  NOV  2000)  [jargon]: 
 
  glitch  /glich/  [very  common;  from  German  `glitschig'  to  slip, 
  via  Yiddish  `glitshen',  to  slide  or  skid]  1.  n.  A  sudden  interruption  in 
  electric  service,  sanity,  continuity,  or  program  function.  Sometimes 
  recoverable.  An  interruption  in  electric  service  is  specifically 
  called  a  `power  glitch'  (also  {power  hit}),  of  grave  concern  because 
  it  usually  crashes  all  the  computers.  In  jargon,  though,  a  hacker  who 
  got  to  the  middle  of  a  sentence  and  then  forgot  how  he  or  she  intended 
  to  complete  it  might  say  "Sorry,  I  just  glitched".  2.  vi  To  commit 
  a  glitch.  See  {gritch}.  3.  vt  [Stanford]  To  scroll  a  display  screen, 
  esp.  several  lines  at  a  time.  {{WAITS}}  terminals  used  to  do  this  in 
  order  to  avoid  continuous  scrolling,  which  is  distracting  to  the  eye. 
  4.  obs.  Same  as  {magic  cookie},  sense  2. 
 
  All  these  uses  of  `glitch'  derive  from  the  specific  technical 
  meaning  the  term  has  in  the  electronic  hardware  world,  where  it  is  now 
  techspeak  A  glitch  can  occur  when  the  inputs  of  a  circuit  change, 
  and  the  outputs  change  to  some  {random}  value  for  some  very  brief 
  time  before  they  settle  down  to  the  correct  value.  If  another  circuit 
  inspects  the  output  at  just  the  wrong  time,  reading  the  random  value, 
  the  results  can  be  very  wrong  and  very  hard  to  debug  (a  glitch  is  one 
  of  many  causes  of  electronic  {heisenbug}s).
