One crazy motherfucker. Someone with absoultely no common sense and no concept of life, death, and danger. It is uncommon to have a batshit insane person and extremly rare to have a batshit fucking insane person because they are usually dead.
Normal guy: Damn, the snow is really startin to accumulate, we should head home now before its too dangerous to drive.

Batshit insane guy: What is it? 15 degrees? Lets go camping bitches!
