Twitjack: to tweet the stranger beside you who you happen to notice is also using Twitter.
The girl standing next to me on the train was tweeting on her iPhone so i glanced over and saw that her username was TweetieGirl... so i tweeted "hey @TweetieGirl i like the red sweater you're wearing. hot." My twitjack totally freaked her out.
