Hiberdating means dating in the winter months, or the situation that someone ignores all their other friends when they are dating a boyfriend/girlfriend. The second meaning is more popular. The word hiberdating is a blending of the word “hibernating” and “dating”, which means a person is in a state of inactivity(hibernating) among friends when dating someone.

Hiberdating指在冬季约会恋爱，或者指某人在谈恋爱期间忽略其他朋友的情况，也就是我们常说的“有异性没人性”。第二种用法更普遍一些。Hiberdating这个词是hibernating(冬眠)和dating(约会)两个词的合成词，由此便可知它的意思是一个人在约会恋爱期间中断与朋友联络的状况。

For example:

I haven’t seen or heard from Jennifer since she started hiberdating Teddy four months ago.

自从4个月前詹妮弗跟泰德约会以来，我就一直没有过她的消息。
