Being in a depressed mess, that nobody wants to be around, or be in. Acting, mournful ,or gloomy, But in an exaggerating manner.
You can be a lugubrious person, like ROBERT.
Emily and I were going to attend Shelly's clambake, but ROBERT had to go and ruin everything by being his same old lugubrious self. He was in a pitiful state of lugubriousness, that put me in a very depressing mode. DAMN YOU ROBERT!
