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."
Where it comes from
From barm, the frothy yeast that forms on top of fermenting beer. Something barmy is frothy and bubbling in the head, so barmy came to mean a little mad, scatty or wonderfully daft. Affectionate more than insulting, the word you reach for when someone has a harmless screw loose.
