rapid deceleration syndrome

(abbreviated to RDS)

Term for the effects of travelling at great speed and then hitting an immovable object... such as cuts, bruises, broken limbs, paralysis or death.

Originally military slang, but now used by other groups, for example:
Rock climbers: The effects of falling from a great height.
Cyclists: The effects of misjudging a corner and hitting a wall straight on.

Severe Rapid Deceleration Syndrome or SRDS usually refers to death.

"Is Mike out climbing today?"
"No he took a whipper yesterday, and he's at home recovering from a case of rapid deceleration syndrome"

"I need the day off work to go to a friends funeral - he caught a fatal case of RDS while out biking the other day"

Decelerated

Comes from the word Deceleration meaning slowing down.
(Decelerated) is used as an insult less specific to certain group of people and focused on the act or behavior of someone instead of the word "Retarded" since retarded meaning is seen as an adjective for disability which is insensitive.

You are decelerated!
What was that decelerated behavior for?
What you just did was decelerated.
