The phrase “blue in the face” is an idiomatic expression that refers to a state of extreme frustration, exhaustion, or exasperation resulting from repeated efforts to persuade or convince someone without success. <\/p>\n\n\n\n
When one argues or explains something exhaustively to the point of becoming physically and emotionally drained, their face may turn blue due to the intensity of their efforts. The expression implies that despite their persistent attempts, they have been unable to change the other person’s opinion or behavior. <\/p>\n\n\n\n
