Sprazy is a "special kind of crazy".
Sprazy isn't whacky, wierd or obviously unstable, but rather it's a person who completely lacks the "let it go" gene in one or more situations.
Sprazy is the person that cleans the house top to bottom before the cleaners come.
Or the bloke that can hear an imperfection in his home entertainment system that no one else on Earth would notice.
It's the partner that cannot be late to a party or the friend that is a cheerful joy to be around unless some magical period of time since their last meal has past...
Sheldon Cooper from "The Big Bang Theory" is the fictional embodiment of "sprazy".
