The complete topic is "We can't do it right because we have to do it fast."
A phrase meant to sound a bit foolish. Many times when facing a deadline, decisions are made to choose something quickly and not "right." Some developers are passionate about doing their work the right way even in the face of a management or marketing deadline. Decisions made to do something based on a deadline while foregoing reasonable design, not taking time to find alternatives, or some other DoSomeThing tactics can lead to worse problems in the future than a missed deadline now.
