No, define away! Descriptivism is a wonderful way to examine artifacts of human activity. But be wary of prescriptivism -- because you have defined a category does not mean you have provided a test for membership, especially if there are connotations associated with the original category. Definitions when applied prescriptively have to be looked at from an operational perspective -- _why_ does it matter that this instance belongs to that category?
