Dehydrated Retardation 

The latent condition lurking within motorists that bounds to the fore any time even two drops of rain fall. Drivers suffer a spontaneous loss of understanding regarding friction, momentum, and inertia.

In my rearview mirror I see a car sliding toward me with its bakes locked, the driver of which is clearly suffering from dehydrated retardation. Boom.

undiagnosed retarded 

Also referred to as: "under the radar retard", "genius on the short bus", "functional stupidity", etc...

Someone that exhibits all the signs of mental retardation yet has somehow flown under the radar to date. A person eligible for the Special Olympics yet unaware of their eligibility, even if family and friends around the person see it clearly. A person of limited logic and decision making capabilities that is sometimes able to pass for normal.

Person A: Wait a minute.... what the hell did he do?
Person B: Ralphy quit his management job yesterday because he thinks he can make more money bussing tables
Person A: Ralph is undiagnosed retarded... what did you expect?
Person B: True...
