When your birthday is so close to christmas that people give you one gift for both occasions.

Birthmasukkah

When one has a birthday close to Christmas, so presents are spread out over multiple nights from one's birthday to Christmas, similar to Hanukkah.

Person 1: Dang, that sucks for her. Her birthday is so close to Christmas that she doesn't get many presents.

Person 2: Don't worry about her. She celebrates Birthmasukkah .
