The mercy killing of anyone with the surrname Trump, any registered republican, or anyone who lives in a red state.
"Kenny drove his SUV through the crowd at the Trump rally in Wisconsin. He killed 43 trumptards and wounded a hundred more."

" Oh shit! Kenny is fucked now, I think Wisconsin has the death penalty!"

" LOL! No worries my friend, Wisconsin is a red state, and all of the stiffs are trumptards. It's justifiable homicide. They might even give him a medal".
