gang bang n.
The use of large numbers of loosely coupled programmers in an
attempt to wedge a great many features into a product in a short
time. Though there have been memorable gang bangs (e.g., that
over-the-weekend assembler port mentioned in Steven Levy's
"Hackers"), most are perpetrated by large companies trying to
meet deadlines; the inevitable result is enormous buggy masses of
code entirely lacking in orthogonality. When market-driven managers
make a list of all the features the competition has and assign
one programmer to implement each, the probability of maintaining
a coherent (or even functional) design goes infinitesimal. See

Law.
