look up any word, like sex:
NOUN: A friend you'll see once in a lifetime, but then never see them again. Like you will still remember them, but you will never see them forever more.
Girl 1: Like, and then we hugged and then we became afterfriends!
Girl 2: Man that sucks that Nick is a afterfriend.
Girl 1: Like, I know right? He was so hot!
