Replacement of your intended word by your cell phone's predictive text feature because you failed to space or were too quick (or thought you were) and you were really off a key and your cell didn't know what the hell you meant so it helped you out without your request. Strangely enough, sometimes you appreciate this feature because you can't always spell everything you'd like to say (but the cell can)!
"If you were turning to reach me, I was in the shower. - unrequested predictive text confused your slippery fingers and when you meant to say, "trying," it thought you meant turning. TOTALLY changes the meaning!
