The Hobbits of the Shire developed the custom of giving away gifts on their birthdays instead of receiving them. They use the term Mathom for old and assorted objects, which are invariably given as presents many times over or were stored in a museum (Mathom-house).
Instead of saying "one hundred and twelve" they say "eleventy two" and that with every other three plus digit number (although in Jackson's Trilogy, Bilbo tells the party-goers that it was his One Hundred and Eleventh Birthday).
