Retarder 

Not only retarded by themselves, but their retarded-ness rubs off on those around them.

retardee 

A person who retired into being retarded. A political act in which person represent themselves as being retarded, when in truth they are not. Something akin to putting a blonde helmet on to create a force shield of stupidity around oneself.

(1) WTF. Since when have you become a retardee?
(2) When returning broken goods to the store, or to Amazon.com with the words "I don't know what happened, ... I just turned it on!?" one becomes a retardee.

Retarder 

A retarder is a device used to augment or replace some of the functions of primary friction-based braking systems, usually on heavy vehicles. Retarders serve to slow vehicles, or maintain a steady speed while traveling down a hill, and help prevent the vehicle from "running away" by accelerating down the hill. They are not usually capable of bringing vehicles to a standstill, as their effectiveness diminishes as vehicle speed lowers. They are usually used as an additional "assistance" to slow vehicles, with the final braking done by a conventional friction braking system. As the friction brake will be used less, particularly at higher speeds, their service life is increased, and since in those vehicles the brakes are air-actuated helps to conserve air pressure too.

Friction-based braking systems are susceptible to "brake fade" when used extensively for continuous periods, which can be dangerous if braking performance drops below what is required to stop the vehicle – for instance if a truck or bus is descending a long decline. For this reason, such heavy vehicles are frequently fitted with a supplementary system that is not friction-based.

Retarders are not restricted to road motor vehicles, but may also be used in railway systems. The British prototype Advanced Passenger Train (APT) used hydraulic retarders to allow the high-speed train to stop in the same distance as standard lower speed trains, as a pure friction-based system was not viable.

The truck used the retarder while going down the hill.
