When someone gets tired of fixing incorrectly autocorrected words in text messaging or social media and just goes with it because the audience they are trying to reach will figure out the gist of what you are saying. Considered an accent as most people under 60 understand what you meant, but older people don't and are confused by what you are trying to say.
John's Autocorrect accent was so strong yesterday his grandma flipped out at him on Facebook.
What did his post say?
"Anyone selling girl scout pussies?" We all knew he meant cookies. Poor grandma didn't.
