How it's used

It carries a slightly informal and resigned tone, making it perfect for discussing academic or practical failures among friends. It is rarely used in formal written reports or official school communications.
Examples

Common mistake
Do not use this to describe someone who is actually overweight, as it can be considered rude or offensive in a social context. Stick to using it strictly for failing tests or tasks.
