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.
