re: Best Misused Word In A Sentence You Ever Heard?

Not the most often misused but the word I find misused at the highest percentage is "nonplussed". It is generally used to mean just the opposite of its actual meaning, I assume since in an SAT type breakdown it is difficult to get correct. People hear the word and repeat it at the "right" time but just say something different than they meant then the other person can be confused because while unlikely it may be exactly what they mean.
