手机带给人们最大的便利就是可以随时随地保持通话，而这样的便利同时也早就了一批耳朵粘着手机不放的“手机通话狂”。
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(全称obsessive cellphone use disorder，手机过度使用症)指一个人一直在用手机打电话，无论开车、出门或是在餐馆吃饭，都一直在打电话的状态。
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机看着点路。天啊，她一定得了手机过度使用症啥的。
