Usually for the kids (in school), if they don't buy a lunch at the school for almost $2.00, and it's not crap, then it's a bagged lunch. It can be in one of those brown paper bags... or in a lunch box: a hard one (I'm not talking "horny" you sick bastards), or a soft one.
"I had my Mom pack me a bag lunch," said Jimmy, "I didn't wanna put up with the crap they serve in the cafeteria again..."
