站在考场里唱咆哮
[zhàn zài kăo chăng lĭ chàng páo xiào]
It humorously describes a situation where the user feels so much pressure in an examination room ('站在考场里' translates directly as standing in an exam room) that they feel like singing loudly and furiously ('唱咆哮'), expressing feelings through roaring songs rather than focusing on tests.
