A form of Black power. The name is derived from the fusing of the words Jiggaboo (referring to a Black person, AKA a "nigger") and Gigawatt, which is a unit of power. A Jiggawatt is generally more powerful than a Gigawatt, because the speed of black is always faster. One may determine the Jiggawatt output by affixing an Ohmmeter or multimeter to the subject, prefferbly the nostrils and having them clench a fist.
When we hooked up to a multimeter to Malcolm X to get an estimate of how many Jiggawatt 's he was was putting out per speech; the meter went from "Oh hell no", all the way up to "Fo shizzle"
A monster that resides in a CPU. Shining light on the processor will increase the size of the Jiggawatt, thereby making your computer faster. Always have a mirror on hand in case the Jiggawatt gets too large - a Compact Disc will do - as the Jiggawatt only retreats when shown an image of itself. A Jiggawatt is affected by the number of Hertz in your motherboard. Sellotaping disc drives to yourself upsets the balance of the Hertz and makes it safe to approach the Jiggawatt.
