:spam: [from the {MUD} community] vt. 1. To crash a program by
overrunning a fixed-size buffer with excessively large input data.
See also {buffer overflow}, {overrun screw}, {smash the
stack}. 2. To cause a newsgroup to be flooded with irrelevant or
inappropriate messages. You can spam a newsgroup with as little as
one well- (or ill-) planned message (e.g. asking "What do you
think of abortion?" on soc.women). This is often done with
{cross-post}ing (e.g. any message which is crossposted to
alt.rush-limbaugh and alt.politics.homosexuality will
almost inevitably spam both groups).
