What it means
Means absolutely hammered, properly smashed, the kind of drunk where you're giving heartfelt speeches to strangers and thinking the night bus is a great plan. Not always blackout, but you're definitely sending risky texts and calling it fate. Common round the UK, especially up north and in Scotland, and it usually lands with pride, regret, and a headache waiting.
Usage examples
"Free bar at the wedding was lethal. I was bladdered by nine, started chatting up the DJ, then queued at the kebab shop like it was church."
"Three pints in and Dave was already bladdered, serenading the kebab van with a song nobody recognised."
"We got properly bladdered at the reunion and spent an hour convincing the taxi driver he was our best mate."
Where it comes from
Built on bladder, the body’s liquid store. The image is blunt and very British: drink enough and you are filled to bursting like a bladder fit to pop. From that picture of being brimful of booze came bladdered, a favourite up north and in Scotland for proper drunk.
