Okay, so people from the Northeast that use "wicked" (like in Boston and such): that doesn't bother me so much. It's the surfer-dude use of it I hear among my 20-something co-workers in Colorado that grates. They also seem to use the word "aggressive" to describe just about anything slightly over the top. I had never heard that word used in the context they use it in until recently. For instance, "adding all those raisins to your oatmeal is really aggressive, dude!"

My significant other mixes up "itch" and "scratch". It's kind of funny. Usually substituting itch for scratch, "I have to itch my leg." I've never heard anyone do that other than him!
