A form of narcissism whereas the person not only has an inflated sense of self-importance, but also have lost all connection to reality and facts. A batshit narcissist will conflate their negative or losing position with victory and supreme dominance, while simultaneously blaming anyone with facts or truth of deception and lies.

After the losing 2020 Presidential election, Donald Trump melted down and became the epitome of a batshit narcissist.

Past the point of insanity, past the point of rationality. Incorperates both the meanings batshit and loco but on a much higher scale. Just losing it, the day before or maybe the day you are commited permenantly to a mental asylum.
