Start the fight with pre-level units, no using your own units. Fight off about twelve waves of enemies only slightly weaker than you with only a small handful of healing items. And when you're down to your last few flecks of health, the boss visits you and inserts his genitals directly into your open wounds.
Of course everyone else in the world is like "d00d that fite is sew ezy u sukk rorwl".
