From Jargon File (4.3.1, 29 Jun 2001) [jargon]:

  no-op /noh'op/ n.,v. alt. NOP /nop/ [no operation] 1. A machine
     instruction that does nothing (sometimes used in assembler-level
     programming as filler for data or patch areas, or to overwrite code to
     be removed in binaries). 2. A person who contributes nothing to a
     project, or has nothing going on upstairs, or both. As in "He's a
     no-op." 3. Any operation or sequence of operations with no effect, such


     as circling the block without finding a parking space, or putting money
     into a vending machine and having it fall immediately into the
     coin-return box, or asking someone for help and being told to go away.
     "Oh, well, that was a no-op." Hot-and-sour soup (see {great-wall}) that
     is insufficiently either is `no-op soup'; so is wonton soup if everybody
     else is having hot-and-sour.
