Subfloptimal (n): pertaining to a point so insignificant, that the time lost in debate outweighs the potential benefit/cost of any outcome in consideration.
Suppose you’re about to drive to a concert with some friends. Friend A suggests a shortcut. Friend B suggests a different shortcut. Letting friends A and B argue about their shortcuts for five minutes is subfloptimal, because while one shortcut may indeed be better than the other, the time spent arguing is going to slow you down more than just choosing a path and going.
This comes up a lot in software projects. Someone will suggest we rename all our floobs and, instead, call them zorts. You might think “hey, there are good reasons we called them floobs” but if you can tolerate “zorts” without worrying much, the distinction is subfloptimal. It’s easier to just make the change than to argue about it, as long as you’re not one of those people who finds it offensive to call something a zort.
In which case you can go zort yourself.
