Modern: anyone who hates hypocracy and pretense and has the termerity to say so; anyone with the habit of pointing out unpleasant facts in an engaging and humorous manner.
As in "I'm like..." misused to express how one feels or reacts to something by young people. Also the word "Go", as in "I go" in lieu of "I said...", or "I did..." It is improper usage and drives me crazy.
