Get the Phandom mug.
A dangerous, yet beautiful, black hole of outdated inside jokes and millions of 12 year old girls.

You have two sides:
-cringey ass toddlers
-edgy meme lords

There is no greyscale.
Bethany: JESSICA! Grab my sharpie we’re going into London to stalk Dan and Phil

Jessica: Why does she keep doing this, Maggie?

Maggie: She’s a Phandom memeber now. There’s no known cure yet.

Get the Phandom mug.
A term for the Danny Phantom fandom (which has been around long before Dan and Phil).
The fandom includes fanficions, edits, animation, fanart, parodies, and much more revolving around the cartoon Danny Phantom by Butch Hartman.
Fans of all ages are a part of it, not necessarily children, so the content is fairly diverse
Example: "Have you ever watched Danny Phantom?"

"No but I'm pretty invested in the Phandom!"
