Checker cabs – let’s flag them all!

Word’s spell checker doesn’t recognize ‘en route’, flagging ‘en’.
Spell checkers were poorly crafted from jump street, and still seem to be in the process of getting their act together. So, let’s introduce an acronym to mark those that seem to need to whip cracked over them: ‘cab’ = ‘clumsy and broken’. So, such a spell checker would be derisively referred to as ‘a checker cab’. (Retooling an abbreviation for derisive purposes is nothing new, of course. A great example, from long ago, was the retooling by the users of IBM’s ‘CADET’ computer, saying that ‘CADET’ stood for ‘can’t add – doesn’t even try’.)
