Social Dead is any period of time where the Social Thread gets very quiet, and the gaps between posts are enormous.Many users are known to complain about Social Dead whenever it happens, sometimes so much so that the thread starts being active again.

It is a rather common occurrence whenever it is nightime in the US, and at times when many are busy (During the day b/c of school and work), since most of the users in the Social Thread are from North America.

Posts solely saying (to paraphrase) "RIP Thread lmao" become disturbingly common at those times.
