Nose bleed is the expression used to indicate that you don't understand what is being said. Dr Mariclare F of Chronicles from the middle of nowhere said: It is often used in the context of someone trying to conduct a conversation in straight English and struggling mightily with it. (If someone comments in my blog, you give me a nosebleed, I'll say, if symptoms persist, consult your doctor). Just kidding.

A meme is a type of online chain letter where bloggers answer questions or participate in a quiz designed to give a quick overview of the author’s personality.

Blogorrhea is a large number of blog entries or an entire blog comprised of substandard quality or overly verbose content.
