When a man refuses to give you a rim job because of his scrub qualities such as not shaving for over 2 weeks or when they suffer from the addiction of keyboard cleaner.
A true man and partner who provides for his mate through the labored love of cleaning. He isn't afraid to get on his knees and scrub between those tiles and has a collection of varied brushes for specific jobs. He will never argue over who's role or job it is to clean what in the house as long as it gets done, followed by getting you done. Scrub daddies can sometimes be born from traumatic military conditioning and/or narcissistic parents so take precautions. A healthy example of a Scrub Daddy is Danny Tanner from Full House.
