To go monumental is to be infatuated by one's ego to the point of acting in a exaggeratedly pretentious way. People who go monumental say things or produce art that is boring and crappy, while at the same time being ostentatious, overblown and pompous. This often creates a mental breakdown which causes the person who goes monumental to loose all contact with reality, and thus their very existence becomes utterly meaningless.

Guy 2: I know, man. He's gone monumental.
