Coupons you give to your significant other for sexual favors. The coupons are normally non transferable and may be good for "1 Blow job", "1 night of sex", etc. Rations are normally gifted on Birthdays and Christmas. These rations are rarely honored, unless the issuing party is "in the mood", and the expiration date is basically whenever the issuer deems it to be. Ass Rations are normally given when money is tight, and there is an obligation to give some sort of gift for an occasion.

Also referred to as "Sex Coupons"
All my wife gave me for Christmas was a book of Ass Rations.
