Regicide of Coolness

Intro
The "Regicide Of Coolness" plot is about someone related to a main character, the "king" or "queen" of being cool, being introduced to that character's friends and, over time, slowly taking that person's life from them. The new person effectively replaces the main character, making that main feel unwanted by their friends, hence the "regicide" in the title of the plot. Later, the replaced character nearly leaves the Main Cast as they're no longer necessary, but they stop themselves from leaving when their friend gets out.

Plot Sample
After getting out of jail, Guy's friend Joseph is introduced to Guy's other friends. Guy shares how good Joseph is at baseball, fencing, skeet, and coding, all things Guy's friends Hugo, Chase, Ava, and Victor have skills in respectively. Days pass and Joseph has already left a good impression on Guy's friends, spending time with them and doing their favorite activities. Guy tries to hang out with his friends, but they're too busy praising Joseph for how cool he is. More days pass and Guy decides he needs to get new friends because his old ones don't need him. As Guy is going home, a police officer asks him if he's aware of the whereabouts of a Joseph Steele. Guy says Joseph is currently in his house and points the officer in the right direction, much to their delight. Later, Joseph is put under arrest as it's revealed he didn't legally get out of jail — he escaped two weeks ago. Guy is finally free to return to his group of friends.
