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. Sex coupons are normally gifted on Birthdays and Christmas. These coupons are rarely honored, unless the issuing party is "in the mood", and the expiration date is basically whenever the issuer deems it to be. Sex coupons are normally given when money is tight, and there is an obligation to give some sort of gift for an occasion.
Some grocery stores such as Kroger and Meijer offer super-double coupon redemption from time to time. This is when a manufacturer's coupon may be redeemed for two times the face value but generally not more than a two dollar total.
"I had five dollar off coupons and it was super-double coupons day at Kroger so I was able to get five tubes of toothpaste for free."

"Oh, just a sec. Let me make a phone call to insert girl's name. I've got to put these pussy coupons for today."
Food Stamps, especially the older 'paper stamp' kind, as opposed to the new credit card type.
My cousin complained once when he was 5 about how slow the checkout lines move when the people in front of you are using 'mexican coupons'. We laughed so hard we nearly passed out, and I have never used the words 'food stamps' since.
