Stand someone up意思

"Stand someone up" is an English idiom that means to fail to meet or keep an appointment with someone, often intentionally. It typically implies that the person who was stood up was waiting for the other person to arrive, but they never showed up. This can be a rude and inconsiderate action, as it leaves the person who was stood up feeling disappointed or embarrassed. The phrase is often used in the context of dates, meetings, or social engagements, but it can apply to any situation where two or more people have agreed to meet.
