The idea of Latino people overpowering whites probably got Phil so worked up that he went to jerk off before remembering he had his micropenis skinned and shoved inside his body to own the Nazis.
You know what would be hilarious??? Seeing Phil's ugly face when he realizes he can no longer jerkoff (if the surgery even happened). Or better yet, his face when he realizes he can no longer stick anything inside his trench because he refused to care for it, it became septic and infected, then ultimately closed up.
