To make sure that people didn't use too much Omo Liquid, we created Priscilla, Queen of the Domestics. Priscilla makes a rather startling appearance in what would start off as a typical detergents advert, and deliver a loud and vigorous “slap” to the person who is about to use more than one cap of Omo Liquid detergent. This would happen while she delivered her catch phrase: “O, eh, eh. Just one small cap is enough!” The phrase is a popular phrase of caution shared by many African cultures in South Africa. It roughly translates to: “Oh, no, no.”
