R.I.P, short for rest in peace, has long been used online as shorthand for anything that is finished, broken or hopelessly lost, from a game character to a phone battery. In edits the phrase became a caption and a sound cue at the same time, signalling a mock memorial rather than a real one. Creators keep using it because the meaning is instant across languages and contexts: no setup is needed, the audience understands the loss is being played for comedy, and the cue works at the end of almost any fail sequence.
