1 definition by Auto Correct Fail

An acronym which stands for "Auto-Correct Fail".

Used to describe the often-annoying Auto-Correct feature on many smartphones. Unless prevented otherwise, the Auto-Correct feature may choose to transform the word completely, thus rendering the phrase nonsensical. In such situations, the victim often can't be bothered to re-type the corrected sentence and an added apology. This can be rectified, excuse-free, by typing "ACF" followed by your originally intended phrase.
A: "Gassy I finally got the book."
B: "?!"
A: "ACF Yaay I finally got the book."
B: "Oh really?"
A: "USA"
B: "Um..?"
A: "ACF Yaa!"
