funky
adj. Said of something that functions, but in a slightly
strange, klugey way. It does the job and would be difficult to
change, so its obvious non-optimality is left alone. Often used to
describe interfaces. The more bugs something has that nobody has
bothered to fix because workarounds are easier, the funkier it is.
TECO and UUCP are funky. The Intel i860's exception handling is
extraordinarily funky. Most standards acquire funkiness as they
age. "The new mailer is installed, but is still somewhat funky;
if it bounces your mail for no reason, try resubmitting it."
"This UART is pretty funky. The data ready line is active-high in
interrupt mode and active-low in DMA mode."
