你有过胖手指病吗When you interface with any kind of computer that requires manual input (whether by keyboard, or a touch screen) there is the chance for making a mistake.
Such mistakes are playfully called Fat Finger Disease.
我们在操作需要手工输入的电脑（不管是键盘还是触摸屏）时，总难遥会出错。
这些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，通常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？
我一定是输错地址了。
