You love your Pomeranain, which is why your gamerhandle lets people know they've been P0wned by CerebusPom23. Your sig file on your favorite message board references your Twitter account. Your color scheme for your fansite is a subtle variant on your favorite sports teams, each page lovingly coordinated.
If you're a fan/geek, especially if you're heavily online, you've probably got a lot of self-references. Handles reflect interests, websites reference other sites, your cosplay costume is based off of your love of Japanese history, etc.
Congrats. You're practicing one of the skills necessary for career success- self-reference.
