Raise a flag
🔊: laap flag
When someone ‘raises a flag’, it means they were being vocal about their plans or goals, but the end result is completely opposite to what they said they would achieve. The ‘flag’ is a reference to the anime series The Tower of Druaga, where it is a common foreshadowing trope that any character who claims they ‘will go home to get married after this battle’ inevitably ends up dead. So if you tell your friends you’re going on a diet, but end up eating ice cream in front of the telly, that’s a ‘raised flag’.
