  bum
       
          1. 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 elder days, John McCarthy
          (inventor of Lisp) used to compare some efficiency-obsessed
          hackers among his students to "ski bums"; thus, optimisation
          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.  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          Usage: now uncommon, largely superseded by v. tune (and
          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 "bum" is a rude synonym for
          "buttocks".

From Jargon File (4.3.1, 29 Jun 2001) : [ 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     superseded by v. tune (and n. tweak, hack), though none of these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.
