No-Op

[no operation]

n. 1. (also v.) 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).

See also JFCL.

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.
