I talk about it honestly. To be honest, I almost talked about it in an interview for a real job, because some of the skills I showcased as an SMJHL GM directly relates to my career. Also, the nerd street cred that comes from being able to say "hockey D&D" is INFINITE.

If I were to make something up, I might say something like Shadowfell Hero Legion, and say it's the name of my D&D campaign. People accept ttprgs a bit better than... whatever the heck we're doing.
