seg fault

A segmentation fault occurs when a running program tries to get at memory that has not been allocated to it and causes a failure. If Martha Stewart was a geek, she'd call this A Very Bad Thing. As used on the channel by KidKero (and extensively in the hacker and jargonist crowds), seg fault (or its long form, segmentation fault) is used like 1/0 to indicate shock, disbelief, mouth-agape, etc. (dist. from: seguementation fault)
