A new word for an old failing.

I want to introduce a new word into the vocabulary: onlyism. A person guilty of onlyism is an onlyist. He or she is that incredibly rude person who seems to feel they are the only person in the world or at least the only one that counts. You see these people every day in 10-items-or-less lines with 15 items, illegally parking in handicapped zones, trying to get to the head of a queue, talking or checking their brightly lit cell phones in a movie theater during the film. You see them in increasing numbers every day. The onlyist I saw today was at Starbucks. She sat down in a chair right next to a man who was quietly working on his computer. She immediately telephoned a friend who appeared on her screen and they began a loud conversation which was obviously distracting to her quiet neighbor. I noticed this from across the room. She didn't, of course. How could she? She's an onlyist.
