Quack 

A more simpler and more generalization of the term is when someone starts explaining the formula of e equals mc squared, when nobody even asked for it and/or cares. Basically someone who never shuts up about anything medical, technological, biological, historical, logical, how great a movie is, how great a game is, why someone is so cool, alright alright, you get the point.

Major Zero: She was originally named Quack.
Naked Snake: Because she never shuts up.
Major Zero: Yes, that's exactly it.
Paramedic: No it's not. Snake tell him.
Naked Snake: ...Gotta go.
