Looking specifically at the question How do we deal with borderline questions during contest week?, and some others, it occurs to me that SA could use an official lexicon. A dictionary of cooking terms (broil, cocktail, marinade) for which the definitions are relatively clear but sometimes misused, like on Should I BBQ chicken on foil?. Once established any use of those terms can be automatically treated as a smart tag in any question, answer or comment. For some terms where the definition is somewhat different than the way it is used as a tag, both could be shown. Cocktail would be a good example, the definition of cocktail is much more narrow than its application as tag.
Of course there will be terms for which there is some dissent regarding "the" definition, BBQ for instance, but there are far more for which a short/simple definition could help clarify questions and answers.
