ボケ

n. A profane word in the Japanese language that's equivalent to calling someone a retard in English. In Japan, it is rarely used, except in some sarcastic joking dilemmas, or when someone's doing something that completely messes up everything, typically a group project. However, this word can sometimes be heard/seen in common manga or anime, typically shounen anime where it's more action oriented. This word is often used with Katakana, or "fragment kana"; a writing system in Japanese to emphasize things or refer to foreign loan-words, such as ケタイ (r. ketai, means cellphone), カメラ (r. kamera, literally) or even Japanese words that can be simplified, such as メガネ (r. megane, meaning eyeglasses).
