Bench friend 

That friend that isn't quite good enough to be the first call when you have something cool happen. They only get the call when the First string friend isn't answering.

I just banged Tanya and her sister at the same time... I gotta call my boy and tell him.

Dam he didn't answer..... who is my bench friend. I'll call him.

friend-bench 

the place you go when the person you are romantically interested in tells you they want to just be friends.

a strategy that rarely works where someone continues being friends with their romantic interest thinking they have a chance to get with them, even though the other person blindly hooks up with everyone but them because they are "such good friends"

Stan got relegated to the friend-bench again when Samantha hooked up with John at the end of the night even though Stan chatted her up for four hours.

beach friends

Special friends who have summer homes on the beach that you can call when you're in your 50s and freaking out about something you did when you were 14.

When she was "panicking” Christine called her beach friends who urged her to call newspapers or her congresswoman.
