Metric Chassis 

The General Motors G-Body platform (1978-88 Chevy Monte Carlo, Buick Regal, Pontiac Grand Prix, Oldsmobile Cutlass). "Metric Chassis" is the name given to these cars by dirt track racing enthusiasts because they were the first GM car to start using metric fasteners.

Tom is running a metric chassis but most others have a Camaro at that track.

Just a group of fellas who respect the frame of a car.

That kid is going ape shit. He must certainly be a chassis boy.

twisted chassis 

Person with observable skeletal asymmetry, resulting in weird swinging when walking.

At first, I couldn´t dig such a weird swinging, then I realized that Gabriela has a twisted chassis.

Chassis 

A person's (usually a female) body. Derived from the frame (chassis) of an automobile. Almost always a positive reference.

Under Chassis Superwash 

When a man is having sex and their partner is riding them on top...at the moment of orgasm, he pulls out and shoots an enormous amount of semen wiping away any trace of tummy sweat, grime or greasy lubricant.

After waiting 6 months to consumate their relationship, Beto pulled out and gave his girlfriend an unforgettable Under Chassis Superwash.

When Felipe performed an Under Chassis Superwash on his girlfriend, he said the amount of semen splashing her stomach reminded him of a fire-hydrant after getting runover by a rookie driven squad car.
