mechanic hand 

Ramming your fingers into a girl's rectum, causing your fingers to look as if you are a mechanic.

I just got so much shit under my finger nails, I look like I have a mechanic hand.

mechanic's lean

To quote wikipedia.com: "A mechanic's lean is a security interest in the title to property for the benefit of those who have supplied labor and/or materials that improve said property. The lean exists for both real property and personal property. Said security interest entitles said mechanic to physically rest his back or shoulder against said item of property (resentful scowling and indignant arms-folding optional) until such time as said property's owner shells out correct payment for said property-improving labor and/or materials."

The primary purpose of outlawing running-boards on most modern vehicles was not for safety-reasons; it was to discourage garage-repairmen from performing mechanic's leans on said vehicles while people were trying to drive around town.

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.
