"Juice" has always driven me crazy. I once visited a friend who has kids and he kept talking about his "juice" when his daughter pipes up and says "daddy I want some juice!". The next 5 minutes were spent with him trying to explain to her that it was his juice, not her juice, and she should never touch his juice but her juice was still okay to drink. Her mother brought her some apple juice and she refused to drink it because she still wasn't sure what the difference was and she was afraid to drink daddy's juice. It was mind-numbing and he still refused to call it "liquid" or anything otherwise.
