Melodrama
A melodrama was a type of literature noted for its characterizations and action. To be melodramatic was to over-dramatize one's situation by acting as though it were more dire than it was.
In 2258 of the alternate reality, seeing James T. Kirk wake up slowly from his unconsciousness, Doctor Leonard McCoy quipped, "Oh, don't be so melodramatic. You were barely dead." (Star Trek Into Darkness)
In 2346, while Kira Nerys was using the alias of Luma Rahl to determine the truth about her mother Kira Meru's liaison with Damar, she questioned how a Cardassian legate knew what Damar was going to say before he said it, the legate explained that he had seen the same melodrama play out several times before.

In 2365, Lwaxana Troi chided her daughter Deanna Troi for being melodramatic after Deanna accused her of scheming. (TNG: "Manhunt")
In 2373, after Jadzia Dax described The Hunchback of Notre Dame as being too melodramatic for her liking, Benjamin Sisko described Victor Hugo's other novel Les Misérables as a 19th century French melodrama. He reasoned that Michael Eddington, through his leadership of the Maquis, was essentially living out his fantasy, with himself cast as Jean Valjean. According to Sisko, the best melodramas involved the villain forcing the hero to sacrifice himself for those he cared about and the cause he was fighting for. This inspired the captain to become the villain in Eddington's story. (DS9: "For the Uniform")
