It means what?
I yell 'Guardy loo!' when tossing laundry over the balcony to get it towards the basement laundry room without lugging it down the stairs. I don't think twice about it. But my husband thinks I'm a bit on the loopy side. He's learned that it means 'falling objects' however, so I guess I'm not completely out of my tree with it. But it's fun.
