friend's friend

For example, a person might not ever encounter their friend's friend, who lives on the other side of the world.

“If it’s not my friend, it’s my friend’s friend.”

Some did eventually show up, but the vibe of the gathering can best be captured this way: When I complimented another attendee’s dress, she immediately showed me that it had pockets, and then her friend offered to share a coupon code for the store that sold the dress, and then her friend’s friend said she actually owned the dress in blue but it never fit right so she was happy to just give it to me — what was I, 5-foot-5?

First, I spent 30 minutes on the phone with a friend’s friend whose husband has brain cancer.

Your friend’s friend’s manners, as well as her dinner, are in need of a trim.
