A variation on "the shocker." The electric chair is where the top wears a strap-on above or below his actual member (or, if the top is a woman, two strap-ons) and penetrates both the anus and vagina.
Dude, I got a strap-on as a white-elephant present at the nursing home. Linda better not misbehave tonight or I'm giving her the electric chair.
