I cringe when I hear the past tense of "impact" used as a verb. The only use for this word should be in relation to wisdom teeth!

"Free gift with purchase" ... It's either free with your purchase, or it is a gift. Why must it be both?

I think it is funny/strange that the "word" truthiness appears both on this list and on Merriam Webster's list of top words of 2006. I'm not a huge Stephen Colbert fan, though.
