A girl so fit that you'd go down on her first thing on a one-nighter regardless of her having a shower or not or how many piss-stops she's had during the night while out clubbing/on the lash. Derived from the same burning reaction you get from placing a nine volt battery on your tongue as what you get from going down on an unwashed beaver.
Look at her over there, is she a nine-volter or what?
(other possible uses are upping the voltage to say a 24volter if she's way up there, or likening her to a car battery)
