It's really unlikely that someone born with such a name would live up to it perfectly but here we are.
Lady Stabsworth Z. Backwash III is a character seen in Issue 20 of the comic book series. In her picture, she is seen spitting into a golden and blue goblet and holding a knife. Based on this picture and the quote written about her, she most likely stabs people and backwashes in drinks.
Her hair appears to be blonde, but most of it is tied under a hair net. There is a blue gemstone on her forehead, and her skin is salmon-colored. She is seen wearing a brown shirt with a puffy white collar. There is a larger blue gemstone around her neck.
