Stands for Attention Deficit Disorder.
A lot of people say they have it because they "sometimes have trouble paying attention in class" which is bullshit. That just means you have a boring teacher.
If you REALLY have ADD, then you can't pay attention to ANYTHING. If you try to read, do homework, watch TV, take a test, or listen to somebody, your focus will slide in and out CONSTANTLY. There is also ADHD in which you are also hyperactive.
Most kids will take medicine like Ritalin or Focalin to help them concentrate.

A.D.D. (Anime Depression Disease), is a disease caused from an over stimulation of viewing anime, or anything related, for long periods of time. The effect of A.D.D. is linked with depression, causing the person to consume the anime for as long as they desire and being in a state of low mood and aversion to activity. Since it is a disease, it is possible to spread and infect other people mentally but not physically through any pathogen.
Man 1: "I can't stop watching television, I think I have a disease."
Man 2: "Yeah if it's anime then that is A.D.D."

Attention Deficit Disorder. People who have this are stereotyped to be stupid, idiotic, dumb and get bad grades when most of these celebrities that are very sucsessful have A.D.D., fuck those stereotypes, I got A.D.D. and I almost got straight A's. The only thing thats wrong with me is I have a little bit of a hard time paying attention, I dont say "Ooh look a squirrel" everytime I'm in a conversation. There is nothing wrong with having A.D.D.
Stereotype beliving faggot: Omygosh watsup man?

Me: Not much, almost got straight A's on my report card.

Stereotype beliving faggot: Ohmygosh really? Dont you have A.D.D.?

Me: Yes, whats the big fuckin deal?

Stereotype beliving faggot: Well arent you supposed to be dumb?

Me: Hey bitch, listen real closely most of these celebrities got A.D.D. and they live sucsessful lives. If you say that I'm dumb one more time this pocket knife isnt only gonna be for opening boxes.

Stereotype beliving faggot: But arent you gonna go like, look at a squirrel when you try to kill me?

Literal Hell.
You cant get work done, and then you feel guilty about it, but still cant bring yourself to do the task.
People consistently use the term incorrectly.
Most people with A.D.D. choose to take medication, while some dont.
