Some of us have read all of 'A Song of Ice and Fire'. Others have just seen what's on HBO. Others are in the middle of the HBO series, or in the middle of the books, or both at the same time. Occasionally, people have wanted to talk about events of ASoIaF in general threads, which would result in spoilers that piss people off. Ergo, anything spoilerish related to ASoIaF is referenced as HODOR, in honor of the Stark servant Hodor, who can say nothing but 'Hodor'. The exact origin of this meme is lost to the fog of a time long ago (early 2012), but poster saxattack29 may have started it*.
