Electronics; Alternating Current;
A current which follows the pattern of a Sine wave. The voltage increases, reaches a peak, dips, goes into the negative, reaches a trough, curves up again back through 0 Volts into positive.
A.C. is used as a mains voltage supply because it can be efficiently stepped up and down from the power plant and can be transported through relatively small cables across the country due to the current being stepped down and the voltage increased to around 270kV so you get the same power, but you dont need huge cables. See also D.C.
When someone walked in on me while I was taking a dump while sitting backwards on the toilet, I casually explained that I was just AC Slatering it up, just like A.C. Slater sat in Saved By The Bell

A.C. Slater
Taking a dump facing the opposite direction on the toilet. AC Slater from "Saved By The Bell" was known for sitting backwards in his chairs, so one only naturally assumes this was also how he pooped.
