1. A variety of power glitch
(see glitch); momentary 0 voltage on the electrical
mains.
2. Missing characters in typed input due to software malfunction or
system saturation (one cause of such behavior under Unix when a bad
connection to a modem swamps the processor with spurious character
interrupts; see screaming tty).
3. Mental glitches; used as a way of describing those occasions when
the mind just seems to shut down for a couple of beats. See
glitch, fried.
