You friend promised to meet you, but he didn't turn up. Or a boy promised to pick a girl up at school but she waited and waited but he didn't come.
This happens in many situations but we often see it in a couple who are in love.
In Vietnamese, we say "the girl got climbed up a tree by the boy". In some Vietnamese-English dictionary, it says "the girl got stood up by the boy"
What is the phrase expressing that someone promised to meet you, but then canceled the meeting without telling you in advance?
