The Great Depression 

The Great Depression, also known as 8th Grade, is the most edgy year of someone's life. From this point on, you will only go down hill into the memes and tumblr pages. You WILL tell your parents that gaming is not a phase, and that "I need to be experimental like everyone else". You will also start to do what you think is cool amongst High Schoolers, but is really only done by the typical Sophomore Stoners who always sneak out of class to go to the Sophomore Juul Room. That's about it. That's The Great Depression.

Typical 8th grader being edgy: "I just can't be happy anymore.... **typing a noose**"
Another 8th grader being edgy: "Do it u wont"

High Schooler who already went through the phase: "Aaah, I can already see The Great Depression rising in their eyes."
