What it means
Means crazy or daft, usually in a cheeky, not-that-serious way. If someone’s barmy, they’re acting like they’ve lost the plot, making wild plans or doing something risky or silly. Can be affectionate or mildly insulting depending on the tone, and it’s a proper old-school British word you still hear in everyday chat.
Usage examples
"You’re hiking up Ben Nevis in flip-flops in February? You’re barmy, mate, get some proper boots before your toes fall off."
"You want to swim in the sea in January? You are completely barmy, but go on then, I will hold your towel."
"It sounds barmy, but his daft plan actually worked and we got there in half the time."
"Only a barmy sod would queue two hours for a kebab at half two, but fair play, it must've been decent."
"She's absolutely barmy if she thinks I'm driving to Bristol in this weather just for a roast."
Where it comes from
It goes back to barm, the foamy yeast froth on fermenting beer. In older British English, that frothy image got cheekily linked to someone’s head, so barmy came to mean addled, daft, or pleasantly mad. It’s been around since the late 19th century and still sounds properly British.
