How it's used

This expression is heavily associated with prison culture and is used to ask someone why they were arrested or convicted. It carries a blunt, informal tone that is generally only appropriate when speaking to someone you already know is incarcerated or has a criminal record. Using it with strangers or in formal settings can be perceived as highly aggressive or rude.

Examples

What did you get in for?
What did he get sent to prison for?

Common phrases

Common mistake

Do not use this to ask why someone had a bad day or failed at a task. While 衰 can mean to fail or have bad luck, 衰乜嘢 specifically implies a legal or moral transgression that leads to punishment.
