There is a saying "but can it run Doom?" Because when Doom came out there were a lot of systems that could not do so. So the question was asked a lot and it became embedded in computer culture. Then came the hackers that realised that you get cred by actually running Doom on systems that it was not designed for it. Thus culturally it was passed down over time. Note that the phrase which came later "but can it run Crysis" is similar but Crysis doesn't have its code under an open source licence.
