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.
