Alternate name for Thanksgiving, owing to the sheer amount of destruction to the turkey population just in one day.
"Hey, Chet. You gotta figure there are about 115 million households in the U.S., right? And let's say the majority of those have a turkey on the table. Think about how many turkeys are butchered just for ONE DAY, dude!"
"I know, Hank. Total gobblecaust."
"Happy Gobblecaust! Chew on your turkey, kidfert!"
