A attributive syndrome which only occurs in females between the age of 11-18 years. This syndrome causes females to become self-centered and also makes them think that they will get 4-8 years of anime events which will never happen to occur during their high school ~ university period. People that have been fully taken over by this syndrome will become overconfident, tryhard, and picky. These people will also be subjected to trashy anime tropes such as: Tsundere, Yandere, Dandere, and Yuudere.
"Doctor, my daughter suddenly became extremely self centered, overconfident, and her personality even changed over night! What should I do?"

n.
1)A common slang term used to define oxycontin, a prescription sustained-release opioid-analgesic marketed by Purdue Pharma. It is comprised of the active ingredient oxycodone, and an inert filler. Available dosages range from 10-80mg. 160mg pills used to be available but were pulled from the market. It does not contain acetaminophen as Percocet, Endocet do. This makes it particularly desirable to those who wish to use it for 'off-label' purposes.
