Z-lister is a term for when you edited your phones contact information by putting a letter Z in front of their name on an individual you break up with or have a bad date with someone. Putting a letter Z puts the contact at the bottom of your contacts.
Bob broke up with Tina and now she is a z-Lister. Hey Tom, Mike wants to know if you want to date one of his z-Listers.
