A term describing a Birthday/Christmas gift for someone who was born on Christmas Day when someone gives them one gift to serve as gift for both occasions. Usually a cheap way to get out of having to buy two separate gifts.
"I get ripped off every year! I always get a Birthmas present instead of Christmas and Birthday presents since I was born on Christmas day!"
