Ahmad "Father of Defecation"

Some critics of Egypt have been (following Ahmad Jibril on Aljazeera) referring to Ahmad Abu Al-Ghayt (Foreign Minister of Egypt's Mamluk) as Ahmad "Abu Al-Gha'it." My mother and brother asked me about the meaning of the word. The etyomology is from an old Arabic word "taghawwut" which means "tabarruz", which means "defecation." I thought that you should know.
