look up any word, like ethered:
Friends, usually but not limited to the opposite sex who are more than just friends, but less than lovers. Flirty friends should not be confused w/ “friends w/ benefits” or “fuck friends” as flirty friends actually tend to flirt in public, cuddle, spoon & occasionally kiss rather than engage in fellatio or coital relations. Most flirty friend relationships have a tendency to end in disaster when the male, in most cases, assumes the relationship has evolved into something deeeper & expresses his new found feelings to said partner.
Meg: Hey Laura did u know Daniel & Isabella are no longer flirty friends??

Laura: Why, what happened??

Meg: Daniel came to think of Isabella as more than a flirty friend & told her even though Isabella was only setteling untill here 1st choice became a free agent again.

Lauara: Always happens... they'll prob ignore each other for a while & then occasionally have to exchange tense half hearted smiles from now on.

Someone who is not yet a boyfriend or girlfriend, but is already more than "just a friend."
My flirty friend just texted me and he said he wants to teach me how to play football.
