scribble n. To modify a data structure in a random and
unintentionally destructive way. "Bletch! Somebody's
disk-compactor program went berserk and scribbled on the i-node
table." "It was working fine until one of the allocation
routines scribbled on low core." Synonymous with {trash};
compare {mung}, which conveys a bit more intention, and
{mangle}, which is more violent and final.
