  From  Jargon  File  (4.2.3,  23  NOV  2000)  [jargon]: 
 
  bum  1.  vt  To  make  highly  efficient,  either  in  time  or  space, 
  often  at  the  expense  of  clarity.  "I  managed  to  bum  three  more 
  instructions  out  of  that  code."  "I  spent  half  the  night  bumming  the 
  interrupt  code."  In  1996,  this  term  and  the  practice  it  describes  are 
  semi-obsolete.  In  {elder  days},  John  McCarthy  (inventor  of  {LISP})  used 
  to  compare  some  efficiency-obsessed  hackers  among  his  students  to  "ski 
  bums";  thus  optimization  became  "program  bumming",  and  eventually  just 
  "bumming".  2.  To  squeeze  out  excess;  to  remove  something  in  order  to 
  improve  whatever  it  was  removed  from  (without  changing  function;  this 
  distinguishes  the  process  from  a  {featurectomy}).  3.  n.  A  small  change 
  to  an  algorithm,  program,  or  hardware  device  to  make  it  more  efficient. 
  "This  hardware  bum  makes  the  jump  instruction  faster."  Usage:  now 
  uncommon,  largely  superseded  by  v.  {tune}  (and  n.  {tweak},  {hack}), 
  though  none  of  these  exactly  capture  sense  2.  All  these  uses  are  rare  in 
  Commonwealth  hackish,  because  in  the  parent  dialects  of  English  the  noun 
  `bum'  is  a  rude  synonym  for  `buttocks'  and  the  verb  `bum'  for  buggery.
