[UNIX/C hackers, from the Mexican dance]
n. In C, a wild pointer that runs out of bounds, causing a core dump, or corrupts the
malloc(3) arena in such a way as
to cause mysterious failures later on, is sometimes said to have
'done a fandango on core'. On low-end personal machines without an
MMU, this can corrupt the OS itself, causing massive lossage.
