Fluttershychosis

The state of mind reached when a usually meek, demure, and gentle person is pushed past their limits of frustration, tolerance, or anger, and lashes out in an uncharacteristic and frightening fit of untrammeled rage.

In the "My Little Pony: Friendship Is Magic" Season One episode entitled "Best Night Ever", kind-hearted pegasus-pony Fluttershy's inability to make friends with Canterlot's local fauna causes her to develop Fluttershychosis and chase the panicked animals into a gala ballroom, her gown and mane all disheveled and dirty, madly screaming, "...you're...going...to LOOOVE MEEEE!!"

Fluttershy 

The yellow pony from My Little Pony - Friendship is Magic.
Fluttershy is a pegasus (Has wings) and as her name describes her, she's usually timid and quiet, but she will always stand up for her friends.

She's one of the main characters of MLP, and has yellow fur, turquoise eyes and a pink tail and mane.
Her cutie mark consists of three pink butterflies with a blue body.

Fluttershy also has a passion for animals, and usually spends her time in the forest with them, but she's scared of adult dragons.

She came from Cloudsdale, a city up on the clouds above Equestria. Fluttershy wasn't as good in flying as the others, and was bullied and was called names like Klutzershy, but Rainbow Dash stood up for her.

Fluttershy: ...ʸᵃʸ............wait was that too loud?
