Okay, this is a pretty complicated process.
1. Bring down the console and get to the funname menu, as cola said.
2. Make sure your name is the phrase you want to bind.
3. Get to the console again, and type "bind KEY $name", where KEY is the key you want to bind the phrase to.
4. Reset your name.
5. Aaand you're done. Don't spam much, or everyone will hate you. Also, don't make more than one (poorly-phrased) thread on the same topic, or everyone will hate you. Also, don't chastise others and then fail to practice what you preach. (Or everyone will hate you.)
