Chainwatch is to watch several episodes of a TV series one after the other, the term is an analogy with 'chainsmoke', the practice of lighting a new cigarette for personal consumption immediately after one that is finished, sometimes using the finished cigarette to light the next one.

Chainwatch就是一集接一集地看电视剧，这个说法是由chainsmoke一词类推而来的，chainsmoke指一根烟吸完以后立马又点上一根，有时是用第一根快吸完的烟来点下一根烟。

For example:

She cites sleeping and chainwatching TV as among her favorite activities.

她说她最喜欢的活动包括：睡觉和一集接一集连着看电视剧。
