Filler Friend 

When someone that you barely know has no one they usually hangout with at a social event of some sort, and start acting like your friend.

I'm so tired of being a filler friend >.>

special male friend

Related to the special lady friend, a not-quite-boyfriend of a female.
An ideal application would include the female and male knowing each other for a while, possible having dated for a brief time, still fucking around once in a while, and being generally close friends, but still remaining single.
Originating from the film "The Big Lebowski".

Sally has lots of friends that are male, but only one special male friend.

mutual friend

A girl who has been fucked by two guys (simultaneously or in different points of time) is their mutual friend.

Or a guy who has slept with two girls is also their mutual friend.

- Hey, guess what, I slept with Annie the other night! She was hella awesome in bed.
- Then I guess she’s our mutual friend now!
