时间偷走了你的音讯
[shí jiān tōu zŏu le nĭ de yīn xùn]
The meaning of this nickname conveys regret or nostalgia over someone who can't be contacted anymore. The word '偷走'(took away) is a poetic way of describing loss due to passage of time. '音讯'(news/sound) refers to contact information, such as telephone call, messages, email, etc. In China's culture, there are lots of stories regarding unreturned favors, unresolved longing, or just unfinished communication because two people gradually grew apart over years, thus creating an atmosphere for names like this.
