bread day

Bread day occurs on the same day on which the freshest loaf of bread you own reaches its expiry date. Though it often results from an unwillingness to eat said bread or completely forgetting about it, realizing it is bread day gives good cause to consume a disproportionate amount of bread that day to avoid wasting any of the loaf.

I brought four sandwiches to school today because it's bread day.

"Oh man, me and Todd ate so many grilled cheeses yesterday. Yeah, it was bread day."
