Lethologica

Lethologica is a psychological disorder in which the person, while conversing, is unable to articulate because s/he forgets key phrases or words, which makes him/her appear either slow or look like a deep-thinking intellectual. I think I might have a minor form of this disorder. I get on a roll for a little bit but then forget the word or phrase I had stored in my mind. Also, Charlie Rose. That guy definitely has it.
