look up any word, like hipster:
 
1.
A person that rarely carries cash and routinely pays with a card.

A card-wanker will usually insist that the benefits of not carrying cash justify their 'card-wanker' status but this is a fallacy.

Card wankers will generally need to go to the cash point before nights out or when purchasing items from places that don't accept cards but will typically only draw enough to cover what they think they will spend which is usually slighly less than they actually need resulting in a second visit to the ATM.
Example 1

Paul: Why is it that there always a queue at the checkout when you're in a rush?
Dave: Yeah, I know.
Paul: And the guy in front of me always turns out to be a card wanker.
Dave: I'm paying on card.
Paul: Why?
Dave: I don't have any cash on me.
Paul: You're such a card-wanker.
Dave: (begins weak attempt to justify his card-wanker status)

Example 2

Paul: Anyone up for a pint after work?
Dave: Yeah, I'll go but I need to go to the ATM first.
Paul: It's a pint, It'll cost you less that a fiver.
Dave: I don't have any cash.
Paul: You're such a card-wanker.
Dave: (begins weak attempt to justify his card-wanker status)
