A morbidly obese female, typical to the southern region of the United States, but indigenous anywhere processed food is in abundance. Ma'am-maws (pronounced mam-maw) tend to have many family members (future Ma'am-maws) as well as numerous animals all under one roof. Upon reaching a level of obesity where sex and age seem less pronounced, they will insist upon everyone calling them Ma'am-maw. They will almost always have a southern accent, despite the fact that they can be found all over the world. Ma'am-maws are quite partial to power chairs, sponge baths, children's beauty pageants, cats, daytime television, and of course almond roca.
I wanted some meatballs at the buffet, but some Ma'am-maw cleaned them all out!
