Husbanger is a made up title, although used quite often it is not found in the dictionary. A husbanger is a "contraction" word if you will. Husbanger is the combination of husband + manager. A husbanger is your spouse who also doubles as your manager in some capacity. I have a cake business and my husband is my husbanger. Husbanger job duties can vary depending on what the nature of the business is. Hope that helps a little.
My husbanger is in charge of scheduling all meetings.
