:black magic: n. A technique that works, though nobody really

may be done by cookbook. Compare also {black art}, {deep
magic}, and {magic number} (sense 2).

:blargh: /blarg/ [MIT] n. The opposite of {ping}, sense 5; an
exclamation indicating that one has absorbed or is emitting a
quantum of unhappiness. Less common than {ping}.

:blast: 1. vt.,n. Synonym for {BLT}, used esp. for large data
sends over a network or comm line. Opposite of {snarf}. Usage:
uncommon. The variant `blat' has been reported. 2. vt.
[HP/Apollo] Synonymous with {nuke} (sense 3). Sometimes the

:bletch: /blech/ [from Yiddish/German `brechen', to vomit, poss.

Often used in "Ugh, bletch". Compare {barf}.

:bletcherous: /blech'*-r*s/ adj. Disgusting in design or function;
esthetically unappealing. This word is seldom used of people.
"This keyboard is bletcherous!" (Perhaps the keys don't work very
well, or are misplaced.) See {losing}, {cretinous},
{bagbiter}, {bogus}, and {random}. The term {bletcherous}
applies to the esthetics of the thing so described; similarly for
{cretinous}. By contrast, something that is `losing' or
`bagbiting' may be failing to meet objective criteria. See also
