The phrase comes from the Apollo 13 mission in 1970, when astronaut Jack Swigert reported a spacecraft malfunction with the words "Houston, we've had a problem." It became far more widely known through the 1995 film Apollo 13, which popularized the wording "Houston, we have a problem." Online, the clip spread as a shorthand reaction for technical failures, bad ideas and sudden chaos, much like a buzzer marks an instant loss. Its staying power comes from being short, clear and universally understood.
