electric slide
The act of lubing and slipping a 9-volt battery (perferably of the Energizer brand because they keep going and going) into one's own anus or the anus of an unsuspecting other while performing fellatio.
Ian was busting a move on The Palace dance floor all night. Once he got a few drinks in him he even pulled out his patented move- the electric slide, but I don't mean the dance move.

I was going down on Ian. He wasn't feeling it, so I gave him the ol' electric slide. He promptly blew his load all over my face.
