When you interface1 with any kind of computer that requires manual input2 there is the chance for making a mistake. Such mistakes are playfully called Fat Finger Disease.
大家在操作需要手工输入的电脑(无论是键盘还是触摸屏)时,总难免会出错。这类手工输入时犯的错误就被戏称为胖手指病。
Fat finger here refers to the act of performing a typo, often used when referring to password typos.
这里的胖手指指的是输入错误,一般用来指密码输入错误。
For example:
You didn't get my email? I must have fat fingered the address.
你没收到我的邮件吗?我肯定是输错地址了。
