What's in the box? See whatcha got!

For most of my working life, I've taken lunch rather than buying it in. I still instinctively call my lunch "bait", which mostly confuses people. I shall attempt to use the word lunch throughout this. I rarely take sandwiches; usually my approach is to pick a box, put into it random things I find in the fridge, and call it lunch. So, the question I've been pondering of late... this whole bento box plan. Other than the rather Japanese theme of the contents, what makes my lunch bento-y? Why did what I was formerly doing not add up to the same thing, modulo presentation?
