Laddums
A stupid game where you trick someone into saying 'huh' or 'what' and then you yell 'laddums' like you just won the world
'Huh?' he said. I said 'laddums' and he facepalmed.
'What?' she asked. I said 'laddums' and she laughed like I was a idiot.
He said 'huh' and I said 'laddums' and he threw a chair.
