Person 1: You're such a tool.

A stereotype of movies. If a character is not specifically important to the (movie, game, etc.)'s plot, or simply isn't "good enough", that character is doomed to die by the end of the story.
I'm surprised that Daniel didn't die by the end of that movie. He had a severe case of Side-Character Syndrome, after all.

When someone around the age of 12-15 get engrossed into one topic such as a TV show or video game, and believes they are a part of it in the form of a Character or possessing the powers from the show or video game. In other cases, influences from shows or video games may not even be a cause.
Surprisingly, this is a quite serious phenomenon that happens in real life, and not just something that appears in the show “Chuunibyou Demo Koi Ga Shitai” as where it is most commonly known.
Symptoms may range from full-on costume wearing with quotes used within their everyday conversations, from acting completely normal with only them believing in themselves having some sort of power.
A common example of a subtle version of this syndrome would be kids having thoughts such as “I’m smarter than anyone” or “No one can understand my thoughts, It’s too complicated”.

A person who recently got into Hearts of Iron 4 and now considers itself a WW2 historian, but in actuality has very limited knowledge of the historical events that unfolded.
The afflicted person tends to start holding opinions falling in the slightly more radical left or right depending on the way he likes to play the game due to democracy being crap.
The afflicted tends to dwell in dimly lit basements and has a Nazi Germany or Soviet Union flag hanging next to his pc, it spends most of it's time playing a runs of Ironman on elite difficulty, watching roleplay HOI videos on youtube or watching WW2 documentaries on netflix
