glitch (n.)youdaoicibaDictYouDict
1959, American English, possibly from Yiddish glitsh "a slip," from glitshn "to slip," from German glitschen, and related gleiten "to glide" (see glide (v.)). Perhaps directly from German. Apparently it began as technical jargon among radio and television engineers, but was popularized and given a broader meaning c. 1962 by the U.S. space program.
All you get today is "glitch" wherever splicing occurs. "Glitch" is slang for the "momentary jiggle" that occurs at the editing point if the sync pulses don't match exactly in the splice. [Sponsor, Volume 13, June 20, 1959]
