whiz kid 

A smart-alecky youngster who is always needing to "drain his radiator".

Whiz kids are supposed to be brilliant and talented; makes me wonder, therefore, if they are actually able to attain such exceptional bladder-control dat they can feel da need to pee whenever they choose, rather than merely letting Mother Nature decide when it's "time to go"?

whiz quiz

Slang for a urine test, especially when testing for drugs. I heard this used back in the mid-2000s in Midwestern America, and have been using the phrase ever since. I’m surprised there is only one other definition with predominantly down votes, claiming it’s British slang.
