:barf: /barf/ [from mainstream slang meaning `vomit']
1. interj. Term of disgust. This is the closest hackish
equivalent of the Val\-speak "gag me with a spoon". (Like, euwww!)
See {bletch}. 2. vi. To say "Barf!" or emit some similar
expression of disgust. "I showed him my latest hack and he
barfed" means only that he complained about it, not that he
literally vomited. 3. vi. To fail to work because of unacceptable
input. May mean to give an error message. Examples: "The
division operation barfs if you try to divide by 0." (That is,
the division operation checks for an attempt to divide by zero, and
if one is encountered it causes the operation to fail in some
unspecified, but generally obvious, manner.) "The text editor
barfs if you try to read in a new file before writing out the old
one." See {choke}, {gag}. In Commonwealth hackish,
`barf' is generally replaced by `puke' or `vom'. {barf}
is sometimes also used as a {metasyntactic variable}, like {foo} or
{bar}.

:barfmail: n. Multiple {bounce message}s accumulating to the
level of serious annoyance, or worse. The sort of thing that
happens when an inter-network mail gateway goes down or
wonky.

:barfulation: /bar`fyoo-lay'sh*n/ interj. Variation of {barf}
used around the Stanford area. An exclamation, expressing disgust.
On seeing some particularly bad code one might exclaim,
"Barfulation! Who wrote this, Quux?"

:barfulous: /bar'fyoo-l*s/ adj. (alt. `barfucious',
/bar-fyoo-sh*s/) Said of something that would make anyone barf,
