Powerdisking means watching several episodes of a TV show in a row, usually from a DVD box set. This can be done over several evenings, or a marathon weekend.

Powerdisking（暂译为“连续读碟”）指抱着DVD碟片盒，一集接一集地观看某部电视剧。这种场景通常会持续好几个晚上，或者持续整个周末。

For example:

I missed the first three seasons of Mad Men, so I spent the past two weekends powerdisking all the episodes in order to be up to date for the premiere of season four later this month.

我没看过《广告狂人》前三季，所以过去的两个周末我一直在连着看这个片子，希望在这个月底第四季首映时能跟得上剧情。
