People who go to lunch with a certain group of people on one day of the week, but cheat on them by going out to lunch with another group of people.
"Hey Kelly, do you want to go to lunch every Tuesday?"
"Sure, you are the only one I like going to lunch with."
(You later find out Kelly goes to lunch with another group of people on Monday, making that person a lunch whore."
