Christmas and Easter Catholics

Over at the Curt Jester there's a growing list in the comment box for this post on terms used to refer to those Catholics who only attend Mass at Christmas and Easter. So far we have the following:

- C & E Catholics (Christmas and Easter Catholics)
- Submarines (Because they only surface twice a year)
- Creasters
- Lilies and Poinsettas
- Reindeers and Bunnies

Do you have any others to add to the list?

Update:
- CEOs (Christmas, Easter, and Occasional)
- Bi-habitual (Habitually come to Mass twice a year)
- Two-timers

One person raised the question of whether these Catholics can be held fully responsible for their lack of regular attendance. I think that obviously the degree of responsibility will vary from person to person, circumstances may be such that they are not fully responsible, but that being said, we are all held responsible to live in accordance with God's commandments, which includes keeping holy the Sabbath.
