One who eats until they are engorged...and then proceeds to eat even more, usually resulting in a turkey coma. A glutton -- but a happy glutton nontheless.

"Yeah, I was a total tryptophanatic over the holidays. I think I slept for about 30 hours after I ate that second turkey."

One of those people who always insists on telling everyone that they will be tired after eating turkey because of the tryptophan.
Guy: "Hey guys, you'll all be tired after eating the turkey. You know why?"

Everyone else: "Because of the tryptophan?"

Guy: "No, because of the tryptophan!"

Everyone else: "Yeah, we know that. Everyone knows that. What a tryptophanatic..."

Guy: (to self) "I'm so goddamned smart."
