/glich/
[from German glitschen to slip, via Yiddish glitshen, to slide or skid]
1. n. A sudden interruption in electric service, sanity, continuity, or program function. Sometimes recoverable. An interruption in electric service is specifically called a 'power glitch'. This is of grave concern because it usually crashes all the computers. In jargon, though, a hacker who got to the middle of a sentence and then forgot how he or she intended to complete it might say,
"Sorry, I just glitched".
2. vi. To commit a glitch.
