RDS 

(abbreviation of rapid deceleration syndrome)

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/tree/whatever 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"

RDS 

Random Death Syndrome:
when someone just randomly dies for an unknown or unexplained reason, can also be used as an exaggeration

What!? You're mom died, just like that? No explanation? sounds like RDS to me....

exaggeration:
Then, she just passed out, out of nowhere, for no apparent reason. She must have RDS or something....
