Someone who will go with you to lunch, looks at the check and comments on how expensive the restaurant is, but does not offer to pay the bill.
The Lunch Whore has never heard of going Dutch, but knows the words for "Free Lunch" in seventy-seven languages. The Lunch Whore also steals your wine when you are not looking.
The Lunch Whore is related to the Dinner Whore. In fact, many Lunch Whore's are also Dinner Whores, and a perfect day for them is two free meals. They don't get up early enough to glom breakfast.
Melissa is a Lunch Whore. On Tuesday she goes out to lunch with a guy, eats drinks, but doesn't pay.
She then goes out with the same guy for a free dinner, doesn't even think of paying and then makes out with another guy at the bar.
For Melissa, a Lunch and Dinner Whore, it's been a perfect day.
