Phone-a-friend
A lame ass friend that only calls, but never wants to hang out in person.
He's just a phone-a-friend; he'll talk on the phone with me, but never wants to hang out.
Phone friend
Friends that aren't romantically involved and aren't friends with benefits. They just sit and talk about sex or, more specifically, sex with each other. They also are so close that none of this bothers the other. One or both can be in serious, loving relationships outside of their conversations.
Hey phone friend. I'd fuck you.
Wow really? Right here right now.
*Doesn't have sex*
*Laughs and then goes make out with bf/GF*
