Phonesia may refer to a) The affliction of dialing a phone number and forgetting whom you were calling just as they answer. b) Getting to the end of a list of options on a recorded helpline number, only to forget which option one wanted; forcing them to listen to them again, and in some cases having to redial the number.

　　Phonesia(电话失忆症)可能指a)拨通某个电话号码，等对方接电话时突然忘记你是在给谁打电话;b)按着机器应答帮助热线的提示一直往下听，结果忘记自己要做的操作是哪一个，然后不得不再把整个提示听一遍，有时甚至还得重新拨一遍热线号码。

　　For example:

　　I called my college teacher last night, then I experienced a terrible phonesia that I couldn’t remember her name. It was awful!

　　我昨晚给大学老师打电话。结果遭遇电话失忆症，竟然想不起这个老师的名字了。简直太糟糕了。
