lachlan down
A ridiculous code that people use to say something weird is happening and they have no idea what to do about it.
'Lachlan down' popped up on the screen. I laughed. My friend cried. My boss screamed.
My coworker said, 'Lachlan down,' and I thought it was a joke. Then I saw the fire truck.
In class, the teacher said, 'Lachlan down,' and I thought it was a new math problem.
