explaining or defining matters or events as
absolutes, especially when not considering the subtleties of the situation.
Derived from the line in Starwars: Episode III,

My boss, in his usual Sithian manner, told me, "We HAVE to extend
the roof 5 more feet", failing to realize
that the roof would then touch
the ground.
