What you say when there is a mishap with regards to Mozart's Requiem

Fac! I sang a major third instead of the tritone!

FAC 

Acronym for F'n Auto Correct. Autocorrect seems to frustrate nearly everyone. When sending a text message or email you type in what you want and Autocorrect changes it; you back space and put in what you want again and again Autocorrect changes it. When quickly sending text messages they often get sent with the wrong/corrected word. So Infuriating!

In a hurry, you want to send the message "Wordle in 2 this morning"
Autocorrect changes it to "World in 2 this morning"
You next type in "Wordle" and hit send
Autocorrect changes it to "World"
You next type in and send "WORDLE" it works
You are so pissed off at Autocorrect you type in and send FAC
