Attention K-Mart Shoppers--Fill your DBag

My wife and I are going to K-Mart today to get the last few items recommended on my Army PowerPoint slide: eyeglasses cleaning and repair kits, fitted sheets, handheld mirror, locks for duffle bags, foot powder, talcum powder, surge protector, extension cord, battery-operated alarm clock, etc. All of these items go in the footlocker--the fifth of the five bags that go with me: A backpack, three dufflebags and the footlocker. For whatever reason, the backpack is not counted as a bag and the others are called Bags A, B, C, & D (the footlocker). One of my kids seeing the printed listed noted that the PowerPoint printout for the footlocker started laughing and said, "Dad, this is a DBag?" DBag is a common insult among high school kids. When I was in high school, we used the same insult but didn't abbreviate. According to the Urban Dictionary DBag is most commonly a "playful insult" though it can be nasty. In the 60s I remember it only as a harsh insult. I suppose there is always something to learn about language even when stuffing a footlocker.
