Someone obsessed with Itachi to the point where they worship him. They make the rest of the Itachi fanbase look bad since they're so vocal and uncompromising. When hard evidence is presented, they ignore it to continue fapping off to their hero.

In essence, an Internet Troll who has it bad for Itachi Uchiha.
Don't be an Itachitard, he can lose.

Gah, I'll get banned saying this but you are a fricking Itachitard.
