The phrase became popular online as a general-purpose bracing reaction, shared in short meme edits and soundboards rather than tied to one confirmed movie or show scene. Its appeal is how non-specific it is, so creators reuse it for anything physically or mentally demanding. The clipped, serious delivery makes it function like a modern reaction line in the same way other prepare yourself sounds do, and it continues to circulate because viewers understand the meaning even without knowing the original context.
