From Can't You Get Along With Anyone? A Writer's Memoir and a Tale of a Lost Surfer's Paradise:

Since aging surfer/memoir writers have as much right to come up with syndromesas anyone else, I think I will: The Head Up Your Ass Syndrome, or HUYA Syndrome. According to me, the HUYA Syndrome supersedes all other syndromes and hence prohibits anyone suffering from it from coming up with his own syndrome. So if you happen to be at a psychotherapy symposium or some such - possibly one where people are supposed to get in touch with themselves -and someone is going on about a syndrome he came up with, your job is to yell "HUYA! HUYA! HUYA!" to shut him up. If this catches on it could do some good for this sorry-ass world.
