::I don't think "definition creep" is an acceptable reason to merge grilling and BBQ.  The fact that individuals use the term incorrectly (and grilling is not BBQ, so using them interchangeably is incorrect) is not a reason to use it incorrectly in this article.  I believe the confusion comes from BBQ grills, which have the capability to both grill and BBQ.  That does not make the processes the same, it just means that individuals have integrated the two terms for ease of use.
