"Fuzzy credit card" is a moderately pejorative phrase referring to the costs that a male normally incurs while socializing with a female. An obvious and sophomoric comparison is made between using a credit card reader and the act of sexual intercourse: Sliding one's penis into a woman's vagina will rack up the highest interest rates you are ever going to pay.
1. That woman is a real fuzzy credit card. I'm bankrupting myself just trying to satisfy her desires for gifts and expensive dinners!

2. Dude, I had to dump that chick. I was racking up too many charges on that fuzzy credit card.

3. She sure is enjoyable to be around, but I had to shit-can her, because she ended up being a fuzzy credit card.
