再不疯狂我们就老了再不告白我们就完了
[zài bù fēng kuáng wŏ men jiù lăo le zài bù gào bái wŏ men jiù wán le]
The phrase conveys the urgency of living life to the fullest or declaring one's love before it's too late. It emphasizes the fleeting nature of youth and opportunity, suggesting that if we don't act now, we might miss out on important moments in life.
