Mechanic's Quick Fix
A type of sex act involving a car battery, jumper cables, copious amounts of lubricant and a go-getter attitude. The act involves using the car battery as a means of electro-erotic stimulation, with a non flammable lubricant also being a requirement so that individuals partaking do not get lit on fire.
That guy I went home with last night turned out to be loads of fun once he gave me a good ol' Mechanic's Quick Fix.
