animesia
When you know what anime someone is mentions or talking about, but you just can't seem to remember what anime or which anime it was.
"I can't seem to remember a certain anime that I seem to like."
"What was it about if you can remember?"
"Well it was about some high school boy finds a notebook and if he writes a person's full name down they die or something like that."
"Sounds like you have a case of animesia, Seth."
