Unicorn Syndrome 

A term loosely applied to preteen and young teenage girls who seem to be living half-inside a fantasy world. Symptoms include overuse of makeup (specifically glitter and eyeshadow), taking horse-riding lessons, wearing multiple bracelets and other tacky jewelery, reading medieval romance novels, et cetera. NOT to be confused with goths.

"J.B. put big smudges of purple over her eyes, then rubbed glitter over her cheeks. She's got a serious case of Unicorn Syndrome going on.. I don't think she realizes how stupid she looks."

Lavender Unicorn Syndrome 

Lavender Unicorn Syndrome occurs when, instead of using a characters name or a pronoun, you repeatedly use other descriptors for them, such as "the baker," "the ninja," "the dragon."

Common in Fan Fictions, the term spawned from the Friendship is Magic /fic/ board where writers would refer to Twilight Sparkle as "lavender unicorn" rather than using her name to describe when she was doing something.

"As Twilight Sparkle walked into the room, the lavender unicorn lifted the book from her shelf with a wave of her horn."
That's Lavender Unicorn syndrome right there. We have pronouns for a reason, people.
