放不下就滚
[fàng bù xià jiù gŭn]
This Nickname ('If You Can't Let Go Then Get Lost ('放不下就滚))' conveys toughness, directness, and no-nonsense. It implies that if someone keeps worrying about the past things they cannot put away (e.g., relationship or other matters), they might as well leave immediately and not trouble the holder anymore.
