The phrase "square up" commonly used in modern-day slang, originated in the late 19th century in the United States. It has its roots in the sport of boxing and refers to the practice of two boxers facing each other and aligning their shoulders and feet in a fair and equal position before the start of the fight. This action is known as "squaring off," which eventually evolved into "square up." In colloquial language, "square up" has come to mean settling a debt, obligation, or disagreeing situation to a fair and satisfactory conclusion.
