A "friend" that is made for a small amount of time. A person to talk to in movies or at a event. As soon as it ends. You have no contact and are strangers once again.
" You were talking to that girl a lot during the movie, you get her number?"
" No, she was just a temporary friend"
An individual or a group of people are friendly for a little while until the next day where you never come in contact with them again.
"These new people I met yesterday were just the typical temporary friends."
