burnt end

noun. Form of commenting on facebook whereby a string of bland or awkward comments, typically between two people, end with the last comment being 'liked', invariably due to the other person wanting the conversation to end.

origin: early 21st Century, based on burning the end of a rope to prevent further fraying.
