A road retard is someone who walks into the middle of the road without looking. Often when with a gay best friend who mocks them for being a retard.

Get the smart retard mug.A word that gets liberals, snowflakes, and SJWs triggered. They think this word is a derogatory word and is just flat out wrong. Even though, it is the actual word that’s supposed to be used when describing someone with a disability, they think it’s mean. That’s how dumb these people are sometimes
Guy1: That SJW’s retarded
SJW: Woah, don’t say that! It’s as bad as the N-word
(No it’s not. Not even)

Get the Retardation mug.
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.
