To flirt with friends/or a friend without having the intentions of dating them, most times done when a person has nothing better to do. Sometimes this may be misinterpreted as "real" flirting. Meaning, flirting with the person because you actually liked them.
Friend 1: Did you see her and him flirting today?
Friend 2: No, she doesn't like him. She was just friend flirting with him.
Friend 1: Oh, Ok.
Friend 2: No, she doesn't like him. She was just friend flirting with him.
Friend 1: Oh, Ok.

To flirt with a friend as if you are just being funny, when in fact you are hot for this person. Commonly used to break out of the "just-friends" relationship.

Noun: A friend that you flirt with, even though you would never date him/her, a practice crush so you're prepared when you actually have one.
When Simon was my flirt friend and I practiced on him so much that some of my friends thought we were actually dating.
