The inevitable and unavoidable nap that occurs about 45 minutes after gorging one's self on a Thanksgiving Day turkey feast and 15 minutes into a traditional, holiday football game. The cause of this an amino acid called L-Tryptophan which turkey meat has in abundance.
Where's Daddy? I haven't seen him since Thanksgiving dinner.

He inhaled two full plates of roast turkey, stuffing, mashed potatoes, corn and yams smothered in gravy then sat down by the fireplace to watch the Packers-Lions. The poor bastard fought like hell, but could only make it to the 2nd quarter before succumbing to a full-blown turkey coma.
