Wikipedia definition
2. Jiffy (time)Jiffy is an informal term for any unspecified short period of time, as in "I'll be back in a jiffy". From this it has acquired a number of more precise applications for short, very short, or extremely short periods of time. Known since the 18th century, the word's origin is unclear, though one suggestion is that it was thieves' cant for lightning.
