Blogorrhea is a slang term for when a blogger makes frequent and excessively long posts to his or her blog. Referring to content as blogorhea also suggests that the posts are wordy and/or poorly edited. The term is an adaptation of logorrhoea, defined by the Oxford English Dictionary as “a tendency to extreme loquacity.”
Blogorrhea was one of the original reactions to the new powers that blogs gave people. Suddenly, all of a blogger's thoughts could be posted for the world to see. And all those eyes, whether real or imagined, put pressure on some bloggers to try to come off as more intelligent, more worldly, more philosophical – more everything. The result was blogorrhea.
