You do what you just did. You introduce the word, and then you encourage people to use it. You must market the hell out of your word. Spend millions to get it placed in media everywhere. Pay people to use it. Sponsor contests. If you spend enough, you can buy anything you want, even official recognition for a word. Shoot! I bet that if you wanted it bad enough, you could buy the dictionary of record of your choice, and make them include your word.
