An evolved form of fangirl. She usually uses worse grammar and punctuation than normal fangirls, and she hates everyone that doesn't think her object of obsession is 'teh HAWT'. If she writes fanfiction, she goes out of her way to flame those who flamed her.
My inbox is filled with fanbrat responses to my flames!

A fanbrat is an immature, childish person in fandoms; usually around fourteen or thirteen years old and largely female, the fanbrat bashes characters from anime, books or cartoons heavily.

They also seem to have loads of hatred for female characters for their personality traits, despite the fact that a male character has the same traits. They seem to forgive 'bishies' and provide no reason why they should forgive the male while they bash the female.

The fanbrats' activity can be disturbing sometimes: they threaten the character's life, they threaten a fan of the character, they refuse to listen to reason and they seem to think they can do whatever they want.

A common insult among them is 'slut', despite the fact that they have no proof that charcter they are bashing is sexually promiscuous in any way.

Despite the fact that these characters do not exist, the fanbrat lies about their personality as justification for hating them (see the Kagome definition).
"OMG LIKE INU-YASHA IS MINE AND I HATE THOSE STUPID BITCHES KAGOME AND KIKYO. THEY ARE SLUTS!11"

"Even though there has been no proof that either of them are sexually active?"

"OMG STFU!11"

"...Umm..."

One of the few things that make anime look really bad. Fanbrats are very immature cartoon fans that flame anyone who has a different opinion than them. Usually young girls, they usually go after male anime characters that have dark and troubled personalities ex. Sasuke from Naruto or Shadow from Sonic.
One of my YouTube videos "Pervy Hinata Comics" get spammed because fanbrats tell me I'm "defacing" Naruto by putting in some shippings they don't agree with.

In Video Game fandom, a term used by older fans (usually between twenty-one and forty) to describe younger fans of video games, who they perceive as too immature to properly understand the game in question. Most often seen in japanese RPG fans, but anyone can make an accusation of being a fanbrat.
"You can't POSSIBLY understand how complex Sephiroth burning the town down is, why the fuck are you even playing a great, deep game like this? Go back to playing Halo, you fucking fanbrat. -.-;;;;"

A disrespectful male or female who is a huge fan of either a cartoon, anime, TV show, ship or movie that acts very immature & is very hypocritical as they don't respect the views of those other than them but want theirs (fanbrats) to be respected.
I am tired of dealing with fanbrats. They don't know when to stop their mess.
