A Slip of the thumb 

is an unintentional mistake made whilst texting, either sending the message to the wrong person or not noticing when predictive texting chooses the wrong word, often to embarrassing or very funny consequences.

a slip of the thumb is or perhaps an email sent by a handheld device. You might not notice when your predictive texting selects the wrong word – book instead of cool for example, or nun instead of mum! I have a Spanish friend 'Viki' V-I-K-I, and when I type in her name it comes out ugli, U-G-L-I. A well-known brand of vodka even comes out as poisoned if you’re not careful.

Slip of the thumbs 

When sending a text message and the recipient of the message was not the intended recipient. Alternatively, when you try to reply to one person, and another message comes in just as you're about to reply, and you end up replying to the wrong person. This issue can have detrimental effects.

Girl to married guy: "Hey, what are you up to?"
(Guy is getting ready to reply, when he's distracted for two seconds, during which time, the following message hits his phone."
Wife to her husband: "I made it to Dallas."
(Now husband, thinking he's replying to his girlfriend says)
Husband to his wife (slip of the thumbs): "Nothing, my wife is out of town if you want to sleep over tonight."
Wife to husband: "WTF!?!?!"
