gas: [as in `gas chamber'] 1. interj. A term of disgust and
hatred, implying that gas should be dispensed in generous
quantities, thereby exterminating the source of irritation. "Some
loser just reloaded the system for no reason! Gas!" 2. interj. A
suggestion that someone or something ought to be flushed out of
mercy. "The system's getting wedged every few minutes. Gas!" 3.
vt. To flush (sense 1). "You should gas that old crufty
software." 4. [IBM] n. Dead space in nonsequentially organized
files that was occupied by data that has since been deleted; the
compression operation that removes it is called `degassing' (by
analogy, perhaps, with the use of the same term in vacuum
technology). 5. [IBM] n. Empty space on a disk that has been
clandestinely allocated against future need.
