OCUD (Obsessive Cellphone Use Disorder) describes a person who continually talks on their cellphone in public, while driving, checking out, or eating in a restaurant.

OCUD(全稱Obsessive Cellphone Use Disorder，手機過度使用癥)指一個人一直在用手機打電話，無論開車、出門或是在餐館吃飯，都一直在打電話的狀態(tài)。

For example:

I wish that lady would get off her cellphone and watch the road. Gosh, she must have OCUD or something.

我真希望那位女士能放下手機看著點路。天啊，她一定得了手機過度使用癥啥的。
