These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Epileptic Trees: A whole forest was planted before The Black Parade was released, resulting in lots of Wild Mass Guessing. Come to think of it, the forest might still be expanding, as there's no real agreement on whether it's the story of The Patient as he's dying or after he dies.
And now there's a whole new forest being planted surrounding the new album! This place has coverage on what's been going on.
Wouldn't it be Epileptic Cacti since the new stuff seems to be taking place in the desert?
Approximately 3 years later: that would be Danger Days, ladies and gentleman. Which is indeed set in the desert.
It got to the point where the band begged people to stop writing stories where they have sex with each other.
Memetic Mutation: Gerard will smash your face in for six bucks and a Dr Pepper. He'll also break into your house and suck your blood if you illegally copy I Brought You My Bullets, You Brought Me Your Love.
"My Gun fires seven different shades of shit. What's your favorite color, punk".
"IN A BAAAAAAAAAHHHHHWWWWWWKKKKSS".
"BUT THERE'S SHIT THAT I'VE DONE WITH THIS FUCK OF A GUN". Pointless, ridiculous, hilarious.
Narm Charm: The "Na Na Na" video and "Art is the Weapon" trailer.
Nightmare Fuel: Gerard's really rather good at this on stage, able to seem potentially Ax-Crazy before looping back into just Crazy Awesome or even Badass. Song-wise, "Mama" and "Bury Me in Black" could qualify.
No Yay: I'm lookin' at you, certain members of the fanbase. You know what I'm talking about.
For those not in the know, Gerard and Mikey Way? They have the same last name because they're brothers. Not because they're married. Because they're brothers. And that's why they love each other. Because they are BROTHERS.
I don't think anyone has any illusions that they're being paired because they're married...
"Stop Having Fun" Guys: The sentiment of a lot of fans (especially on LJ) in response to the "shenanigans" the band is doing before the release of the 4th album, directed towards both the band and the fans who want to actually participate in the shenanigans.
