What Does "Batshit insane" Mean: Definition and Examples

Street voices

"Batshit insane, sometimes shortened to simply just batshit, is a hyperbolic way of saying someone is crazy. Dude, did you see that stunt Marcel did where he drove his bike off a cliff? Oh my god yeah I saw that, he's batshit insane."

What it means

Batshit insane is a loud, hyperbolic way to say someone is completely crazy, reckless, or operating with zero fear and even less common sense. People also shorten it to just batshit when the madness is already obvious. It is rude, casual, and built for moments when normal words feel too polite for the chaos in front of you.

Usage examples

"Did you see Marcel launch his bike off that cliff for a laugh? That bloke is batshit insane and someone needs his car keys."

"Queuing overnight in a storm for a phone is batshit insane, said the bloke who did it twice."

"The traffic at rush hour is batshit insane, I aged a year just getting across town."
