1) battery used to back up an alarm clock in case the electricity goes out, insuring that the alarm will sound in one hour and twenty minutes. The exact time it takes to get hard again. Normally you wouldn't care but this pie is an unbelievable ram and you can't risk the alarm not going off, like your hog.
Hey Pinjat, give me a pack of reds, a dozen horses and a nine volt. And yea, I will have some of your beef jerky even though you pray to it.
This is a pussy that tastes so bad that you recoil in horror after sticking your tongue on it. Much like what happens when you put your tongue on a 9 Volt Battery.
A sex technique much similar to scissoring except with two men. Both men assume a sitting position while laying on their sides, then they back their asses up to each other and insert their penises into the other's butts.
Dan isn't a bitch when it comes to gay sex, he likes nine volting, so it is all mutual.
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)
