Snowflake

A song from a game, tv show, movie, or other media, that brings upon intense emotion. Most times the emotions are bitter-sweet, as you're remembering all the fun you had consuming that media.

The word comes from the song in Persona 4 Golden, which makes almost anyone who's played the game feel very intense emotion.

"I decided to listen to Swear To My Bones, and I started crying... that song is really a Snowflake."

Door

A person who often doesn't show heavy emotion or have large reactions
